Abstract

Abstract: Wide area surveillance-ground moving target detection (WAS-GMTI) mode is one of the important modes for most multi-functional airborne radar. System design of the WAS-GMTI mode can affect the final moving targets detection and tracking abilities to a great extent. Therefore, research focuses on the system design of multi-channel WAS-GMTI radar system. The expression of WAS-GMTI radar echo (including the crab angle) is derived. Signal to noise ratio (SNR) and clutter to noise ratio (CNR) are presented. These are the preparations and foundations for the further discussion. Four key points are detailedly analyzed in the process of system design of WAS-GMTI radar, including range walk and range curvature analysis, clutter spectrum analysis, multi-frequency system and multi-PRF system analysis, number of pulses per burst analysis. Besides, these four key points are simulated and some conclusions are drawn after each discussion.
