摘要
Abstract
Based on geometric relationship among platforms and character analysis of general bistatic SAR, expressions of Doppler parameters of general bistatic SAR system are presented in the paper. Analysis shows that the difference between the motion vector of transmitter and receiver cause the different image configuration for different point target in azimuth. So the Doppler parameters change with the different target and echoes spectrum is also different from the azimuth-invariant configuration and the algorithm must compensate two-dimensional variance. The simulation results verify the characteristics of variance. The conclusion deduced from the paper would be one basis for choosing the system parameters and focusing algorithm.关键词
