A Novel Method of ISAR Imaging for High Speed Targets using Stepped-Frequency Chirp Waveform

摘要：

In this work, a method of ISAR imaging is proposed for high speed targets using stepped-frequency chirp signal. Keystone formatting is applied among pulses which have identical carrier frequency to eliminate range migration. The range-Doppler coupling and range-profile broadening is compensated by means of processing via Doppler channel division. Simulation results demonstrate the effectivity and adaptability in low SNR condition.
