Synthetic Aperture Radar Pulse Compression and Processing for High Resolution Imaging

  • Mina Kamal


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.
