Efficient, Closed-Form Computation of Airborne Pulse-Doppler Radar Clutter

摘要

Closed-form expressions are derived for airborne pulse-Doppler radars to calculate the ground clutter of a range-Doppler cell under the flat earth assumption. These expressions enable accurate and efficient computation of both radar sidelobe and main lobe clutter for an arbitrary combination of radar pulse-Doppler waveform and low altitude flight configurations as defined by platform speed and dive angle. The results should be useful in the simulation and evaluation of airborne radar performance.
