Process for sensor resources management
First Claim
1. A process for tracking nominated moving vehicles and at least one other vehicle by means of a radar system within an aircraft, the radar having moving target indicator, high range resolution and high update rate modes of operation, the process comprising the steps:
- tracking the kinematic quality of the vehicles by calculating position, heading, and speed uncertainty of the vehicles and providing a first set of scores therefore;
collecting data needed for future required disambiguations by calculating the usefulness and neediness of identification measurements of all tracked vehicles and providing a second set of scores therefore;
collecting required data needed for immediate disambiguation by calculating the usefulness and neediness of identification measurements of all ambiguous tracked vehicles and providing a third set of scores therefore. selecting the highest over all score of from said first, second and third scores; and
cueing the radar to track the vehicle with the highest over all score to operate in the high update rate mode or, high range resolution mode, or moving target indictor mode depending upon which score is the highest score.

Abstract
The subject process accepts the data from a kinematic tracker and maps them to fuzzy set conditions. Then using a multitude of defined membership functions and fuzzy logic gates, generates sensor mode control rules. It does this for every track and each sensor. The Rule with the best score becomes a sensor cue, which is used to place the sensor into one of three operating modes. If there are ambiguities do to one or more vehicles coming in to close proximity to each other process compares radar profiles of vehicle to those stored in an “on the fly” data base to eliminate the ambiguities.

12. A process for tracking nominated moving vehicles and at least one other vehicle by means of a radar system within an aircraft, the radar having moving target indicator, high range resolution and high update rate modes of operation, the process comprising the steps:
-
tracking the kinematic quality of all vehicles by calculating position, heading, and speed uncertainty of the vehicles and providing a first set of scores indicative of the need for monitoring a particular vehicle;
collecting data needed for future required disambiguations by calculating the usefulness and neediness of identification measurements of all tracked vehicles and providing a second set of scores indicative of the need for monitoring a particular vehicle;
collecting required data needed for immediate disambiguation by calculating the usefulness and neediness of identification measurements of all ambiguous tracked vehicles and providing a third set of scores indicative the need for monitoring a particular vehicle;
