Abstract

Synthetic aperture radar (synthetic aperture radar, SAR) use a two-dimensional matched filter to improve the signal to noise ratio but the signal-to-noise ratio (SNR) gain of synthetic aperture radar (SAR) is controversial. The traditional method analyzes the SAR signal-to-noise ratio based on pulse compression and coherent integration, but it will have different calculation results. In this paper, in connection with the characteristics of the SAR digital signal processing, the SNR gain of the two-dimensional matched filter is derived to solve the contentious issue of SAR signal-to-noise ratio which is based on the assumption of the band-limited white noise in the digital domain, and the impact of matched filtering on SNR is analyzed and the optimized design criteria of sampling rate is presented. This conclusion of analysis is verified by simulations, which provides a theoretical basis for the SAR system design.
