Abstract: Ground moving target indication (GMTI) in the synthetic aperture radar (SAR) system enables high-resolution, all-weather, and all-day imaging and detection of moving targets, posing a ...

A hybrid phase demodulation structure combining a 3 × 3 coupler and Sagnac interferometer is proposed to improve the spatial resolution and phase demodulation performance of the phase-sensitive ...

Abstract: Phase modulation jamming (PMJ) alters the characteristics of radar echo signals through multiplicative time-varying phase modulation, thereby degrading the performance of conventional radar ...
