Abstract:
1. A method of operating a multibeam radar carried on a platform flying a mission over a prescribed flight path to obtain images of a plurality of target areas, the beams of said radar being the result of respective transmit pulses and beam returns being received by respective receive windows, comprising the steps of: providing a plurality of data relating to said mission and said radar; from said data, calculating a plurality of parameters related to the geometry of the flight of said platform as well as the operation of said radar, including the calculation of a range of PRFs and PRF change rates to be utilized in an iterative process; performing said iterative process to determine a non-collision alignment of said transmit pulses and said receive windows; utilizing said PRFs, PRF change rates and said non-collision alignment to simulate a flight of said platform over said prescribed path to determine, for said alignment the dwell time until a collision occurs; utilizing in an actual said mission said PRF, PRF change rate and said non-collision alignment which provided sufficient said dwell time to obtain all said images.
