Land Clutter Characteristics Analysis of Low Altitude Flight Radar Platform

Abstract

During the operation of the low altitude radar platform, the test of electromagnetic environment from the surface is becoming more and more severe, which has directly affected the various performance of radar detection. The land clutter is not only an important component of the radar electromagnetic environment, but also an important feature of the radar electromagnetic environment, therefore, it is necessary to measure and analyze the characteristics of the land clutter. In this paper, a small unmanned aerial vehicle (UAV) is used as a carrier to carry a certain type of pseudorandom code continuous wave radar for land clutter measurement, the clutter characteristics of the measured terrain are analyzed according to the amplitude distribution, temporal correlation and spatial correlation of land clutter, so as to get the statistical feature of the land clutter under different measurement conditions.
