双站SAR雷达目标旋转部件的微多普勒效应
Micro-Doppler Effect of Target with Rotating Part in Bistatic SAR
摘要
Abstract
Based on the configuration of Bistatic side-looking SAR with parallel track, the signal model of radar target with rotating part was provided, and then the mathematical expressions of micro-Doppler and its chirp-rate induced by target rotation were derived. The analysis indicates that the micro-Doppler effect is not only related to the parameters of micm-motion and carrier wavelength, but also the aystem geometrical configuration. So the micro-motion target indication ability can be improved by changing the geometrical configuration, while preserving relatively high viability of the system on the war-field. Finally, the theoretical analysis is verified by the simulation results.关键词
