Synthetic Aperture Radar Pulse Compression and Processing for High Resolution Imaging

  • Mina Kamal

Abstract

This paper aims to design a transmitter and a receiver system for a synthetic


aperture radar (SAR) to be used on either an aircraft or a LEO satellite for high


resolution imaging on the earth’s surface. The transmitted pulse is to be shaped and


modulated before transmission. The construction of a compressed time domain echo


pulsed signal in the receiver is shown to improve the range resolution without side


effects on the signal to noise ratio by using a matched filter. Also a particle swarm


optimization (PSO) algorithm in the matched filter design is used here for different


higher orders of polynomial instantaneous frequency modulation to reduce the


sidelobe levels of the autocorrelation function at the output of the matched filter that


represent the undesired targets with respect to the main lobe level that represents the


desired target in the received echo pulse. The PSO algorithm and its results are shown


by using MATLAB program codes.
