摘要
Abstract
A novel method of ISAR imaging for high speed moving targets is presented in this paper. The phase-coded signal bears favorable resolution in range and velocity, however it is sensitive to Doppler frequency, and Doppler phase should be compensated before pulse compression. For the high moving target, the envelop stretch must be considered especially. A movement compensation method combining wideband phase-coded signal and narrow band linear frequency modulated signal is introduced. The narrow band signal is applied for detection and measurement, while the wideband signal for improving the speed accuracy and imaging. Simulation results prove the effectiveness of this method.关键词
