System and method for filling gaps in radar coverage
First Claim
1. A method of positioning a plurality of additional radar units in a defined area amongst one or more legacy radar units that provide legacy radar coverage in the defined area, the method comprising the steps of:
- identifying a location of each legacy radar unit;
setting a threshold altitude;
determining a legacy occultation of each legacy radar unit from a landscape level up to the threshold altitude;
mapping the legacy occultation of the legacy radar units to provide a three dimensional occultation map in the defined area;
locating gaps below the threshold altitude in the legacy radar coverage as a function of the occultation map;
identifying a plurality of sites as a function of the gaps, wherein the sites are accessible to receive an X band radar unit;
determining an anticipated radar coverage of an additional radar unit positioned at each of the sites;
determining a reduction in the gaps as a function of the anticipated radar coverage; and
selecting sites as a function of the reduced gaps.

Abstract
A method of positioning a plurality of radar units in a defined area amongst one or more legacy radar units that provide legacy radar coverage in the defined area is disclosed. The steps of identifying a location of each legacy radar unit, setting a threshold altitude, and determining a legacy occultation of each legacy radar unit from a landscape level up to the threshold altitude are also disclosed. Mapping the legacy occultation of the legacy radar units to provide a three dimensional occultation map in the defined area and locating gaps below the threshold altitude in the legacy radar coverage as a function of the occultation map are also disclosed. Identifying a plurality of sites as a function of the gaps where the sites are accessible to receive a radar unit is also disclosed. Determining an anticipated radar coverage of a radar unit positioned at each of the sites and determining a reduction in the gaps as a function of the anticipated radar coverage are also disclosed. Selecting sites as a function of the reduced gaps is also disclosed. X band, C band or S band radar units can be positioned at the selected sites. The threshold altitude can be 10,000 or 15,000 feet. Affected populations and costs can also be considered in radar placement.

14. A non-transitory computer readable medium having instructions stored thereon which when executed by a computer, cause the computer to carry out the following steps:
-
receiving input data identifying a location of each legacy radar unit; receiving input data setting a threshold altitude; determining a legacy occultation of each legacy radar unit from a landscape level up to the threshold altitude; mapping the legacy occultation of the legacy radar units to provide a three dimensional occultation map in the defined area; color-coding gaps below the threshold altitude in the legacy radar coverage as a function of the occultation map; receiving input identifying a plurality of sites as a function of the gaps, wherein the sites are accessible to receive an X band radar unit; determining an anticipated radar coverage of an additional radar unit positioned at each of the sites; color-coding the occultation map to reveal a reduction in the gaps as a function of the anticipated radar coverage. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
