Study on High-Resolution Polarization Target Detection Based on Intense Scatterer Range Integration

The problem of target detection in the cluttered circumstance with wide band high resolution radar is studied.A high resolution polarization target detection method is presented based on intense scatterer integration.With the intrinsic high resolution of wide band waveform,one dimension range profile of radar target can be obtained.In connection with target's polarization characteristic,the number and distribution of intense scatterer in radar echoes can be estimated.SCR(Signal to Clutter Ratio) can be improved efficiently by integration of these intense scatterers in resolution cells.Simulated experimental results show that radar's detection performance can be improved significantly by using the algorithm presented in this paper.
