Abstract

Abstract

Synthetic Aperture Radar (SAR) using multiple transmit-receive apertures can obtain wider swath and higher spatial resolution. In this paper, intersection of frequency spectrum is adopted in the SAR imaging using multiple transmit-receive apertures, which can achieve high range and azimuth resolution simultaneously. As for sub-band pulses synchronously transmit-received, a method of sub-band combination in time domain prior to pulse-compression is proposed and sub-band compression prior to combining is proposed in frequency domain as a extension. The simulation result illustrates the validity of these methods. In addition, there exist some phase differences caused by the carrier frequency and their influence on pulse compression and SAR imaging is studied, the computer simulation is made to show the influence.
