Abstract

Abstract:

Helicopter-borne Radar (HeliRadar) has the advantages of full-perspective imaging and short revisit period, which can ensure the rotor aircrafts flight safety at the low altitude. In order to solve the azimuth mismatch problem of the existing algorithm, the HeliRadar imaging algorithm in the frequency domain is presented in this paper. Through the frequency domain analysis of the characteristics of the HeliRadar echo, this new algorithm can obtain a two-dimensional accurate spectrum, construct the frequency domain correction function and the matching function, and achieve the matching imaging. Simulation results verify the effectiveness of the algorithm.

Key words: helicopter-borne radar, frequency-domain analysis, azimuth focusing
