Randomized trial demonstrates enhanced 3D radar imaging precision in non-coherent point targets, indicating improved methods under challenging conditions.
Key Points
The aim is to develop a polarimetric 3D imaging framework for three-channel monopulse radar to enhance the resolution of non-coherent targets.
Utilized a joint polarimetric-angular diversity approach to improve radar imaging.
Proposed a cost function for fluctuation minimization to stabilize angular parameter estimates.
Implemented an optimized oblique projection strategy to separate overlapping echoes.
The proposed method outperformed traditional techniques like MPV, Seung, and Blair in estimation precision.
Significantly improved performance in low SNR and complex scattering scenarios was observed.
Experimental validation confirmed effectiveness in resolving targets against strong non-coherent backgrounds.
