Abstract

A radar system is provided that uses configurable radar control software. The radar system may continually adapt over time to perform different types of radar mission by re-configuring the radar control software with mission specific configuration data. A configuration database may be provided to store the configuration data for retrieval during mission transition operations.

Claims

1. A method for use in operating a radar system that is capable of performing a plurality of different types of radar missions, comprising:

determining, by one or more digital processors of the radar system, a mission type to be performed by the radar system;

retrieving, by the one or more digital processors, a configuration file from a configuration database that is associated with the identified mission type, the configuration database including configuration files associated with a plurality of different mission types; and

using, by the one or more digital processors, configuration information from the retrieved configuration file to configure reconfigurable radar control software associated with the radar system to perform a mission having the identified mission type.

2. The method of claim 1, wherein:

using, by the one or more digital processors, configuration information within the retrieved configuration file to configure, by the one or more digital processors, reconfigurable radar control software to perform a mission having the identified mission type includes using the configuration information to adapt one or more common radar functions in the radar control software for use with the identified mission type.

3. The method of claim 1, further comprising:

repeating, by the one or more digital processors, the steps of determining, retrieving, and using as new missions are performed by the radar system.

4. The method of claim 1, wherein:

determining a mission type includes receiving, by the one or more digital processors, a mission type indication from a radar operator.

5. The method of claim 1, wherein:

determining a mission type includes sensing a hardware configuration of the radar system by the one or more digital processors.

6. A radar system that is capable of performing a plurality of different types of missions, comprising:

one or more digital processors to execute radar control software to control one or more functions of the radar system, the radar control software being configurable to perform different types of radar missions for the radar system; and

a database storing configuration data for use in configuring the radar control software the database having different configuration files that are associated with different radar mission types;

wherein the one or more digital processors are configured to retrieve configuration data from the database based, at least in part, on a type of radar mission to be performed by the radar system and to adapt one or more modules or functions of the radar control software using the configuration data retrieved from the database.

7. The radar system of claim 6, wherein:

the database includes a single configuration file for each type of radar mission supported by the radar system.

8. The radar system of claim 6, wherein:

the database includes a group of configuration files for each type of radar mission supported by the radar system.

9. The radar system of claim 6, wherein:

the radar system includes a single radar control software program to control all supported mission types.

10. The radar system of claim 6, further comprising:

an antenna having one or more motors to controllably rotate or slew the antenna in one or more dimensions;

wherein the database includes first configuration data associated with a first mission type to configure the radar control software to control the radar with the antenna rotating and second configuration data associated with a second mission type to configure the radar control software to control the radar with the antenna held stationary.

11. The radar system of claim 6, wherein:

the database includes first configuration data associated with a first mission type that configures the radar control software to operate the radar at a first target update rate and second configuration data associated with a second mission type that configures the radar control software to operate the radar at a second, different target update rate.

12. The radar system of claim 6, wherein:

the database includes first configuration data associated with a first mission type that configures the radar control software to detect a first type of target and second configuration data associated with a second mission type that configures the radar control software to detect a second type of target that is different from the first type of target.

13. The radar system of claim 6, wherein:

the database includes first configuration data associated with a first mission type that configures the radar control software to scan a large acquisition search area and second configuration data associated with a second mission type that configures the radar control software to scan a small acquisition search area.

14. An article comprising a non-transitory computer readable medium or media having the following stored thereon:

configurable radar control software to control operation of an associated radar system when executed by a computer system of the radar system, the configurable radar control software having a plurality of modules or functions for performing basic radar tasks that can be adapted to different types of radar missions using configuration data; and

computer instructions that, when executed by the computer system of the radar system, operate to;

determine a type of mission to be performed by the radar system, retrieve configuration data from a database based on the type of mission, and adapt at least one of the plurality of modules or functions of the configurable radar control software using the retrieved configuration data.

15. The article of claim 14, wherein:

the non-transitory computer readable medium or media has a plurality of configuration files stored thereon that each correspond to a particular radar mission type, each of the plurality of configuration files including configuration data to adapt one or more of the plurality of modules or functions of the configurable radar control software to perform a corresponding mission type.

16. The article of claim 15, wherein:

the non-transitory computer readable medium or media includes first configuration data associated with a first mission type to configure the configurable radar control software to rotate an antenna about an axis and second configuration data associated with a second mission type to configure the configurable radar control software to hold the antenna stationary.

17. The article of claim 15, wherein:

the non-transitory computer readable medium or media includes first configuration data associated with a first mission type to configure the configurable radar control software to operate the radar at a first target update rate and second configuration data associated with a second mission type to configure the configurable radar control software to operate the radar at a second, different target update rate.

18. The article of claim 15, wherein:

the non-transitory computer readable medium or media includes first configuration data associated with a first mission type to configure the configurable radar control software to detect a first type of target and second configuration data associated with a second mission type to configure the configurable radar control software to detect a second type of target that is different from the first type of target.

19. The article of claim 15, wherein:

the non-transitory computer readable medium or media includes first configuration data associated with a first mission type to scan a large acquisition search area and second configuration data associated with a second mission type to configure the configurable radar control software to scan a small acquisition search area.
