Abstract

In order to accurately identify ground targets from radar observations on distributed airborne sensors, range and range-rate measurement data must be either processed onboard the aircraft or at a common control station. This paper will show analysis and results that examine the ability of multiple sensors to provide observability of moving targets. Extremely accurate states are required to support imaging algorithms used to discriminate military targets from civilian targets. Accurate imaging of targets of interest requires sub-meter range accuracy as well as precise knowledge of the target heading which is related to the velocity vector accuracy. The tracking algorithms must provide range accuracy on the order of meters depending on the target spacing and scenario; the imaging pre-processing algorithms can reduce this error to sub-meter levels. Stringent requirements on heading accuracy may be obviated by the use of prominent point tracking.
