Abstract :
Ground based emitters can be located with a receiver installed on an airborne platform. This paper discusses techniques based on Doppler frequency and differential phase measurements (interferometry). Measurements of the first technique are provided, while we discuss and compare the theoretical accuracy of both. In addition, we demonstrate the use of simulated annealing for finding flight tracks that lead to the smallest location error.
