Abstract

A phase-coded stepped-frequency (PCSF) waveform with high range resolution (HRR) processing is presented as an improvement to stepped-frequency (SF) processing. By combining intrapulse phase and interpulse frequency modulations, the PCSF technique enables larger frequency step sizes than SF processing-system effective bandwidth is traversed more quickly, allowing shorter burst times while decreasing Doppler sensitivity. The PCSF framework presented and corresponding HRR simulation results for complex targets are shown consistent with the ideal SF response and demonstrate Doppler sensitivity reduction
