A Space/Fast-Time Adaptive Monopulse Technique

A Space/Fast-Time Adaptive Monopulse Technique

Mainbeam jamming poses a particularly difficult challenge for conventional monopulse radars. In such cases spatially adaptive processing provides some interference suppression when the target and jammer are not exactly coaligned. However, as the target angle approaches that of the jammer, mitigation performance is increasingly hampered and distortions are introduced into the resulting beam patt...

Space - Time Adaptive Monopulse Processing

A Novel Monopulse Technique for Adaptive Phased Array Radar

The monopulse angle measuring technique is widely adopted in radar systems due to its simplicity and speed in accurately acquiring a target's angle. However, in a spatial adaptive array, beam distortion, due to adaptive beamforming, can result in serious deterioration of monopulse performance. In this paper, a novel constrained monopulse angle measuring algorithm is proposed for spatial adaptiv...

Performance analysis of space-time-adaptive monopulse

The two-dimensional monopulse estimation scheme is extended to spaceand time-adaptive processing (STAP) for arbitrary sum and di2erence beams and arbitrary subarrays in space and time. This includes the case of time samples at the pulse repetition frequency (PRF, slow time STAP) as well as time samples at Nyquist frequency according to the receiving bandwidth (typically samples from range cell ...

Robust adaptive beamforming for MIMO monopulse radar

Researchers have recently proposed a widely separated multiple-input multiple-output (MIMO) radar using monopulse angle estimation techniques for target tracking. The widely separated antennas provide improved tracking performance by mitigating complex target radar cross-section fades and angle scintillation. An adaptive array is necessary in this paradigm because the direct path from any trans...
