Performance Analysis of DPCA Based SAR Moving Target Detection
This paper analyzes the performance of SAR moving target detection based on displaced phase centre antenna(DPCA)method theoretically.The statistical models of multi-looked DPCA metric are established under hypotheses interference(stationary clutter plus noise)only case and the case moving target superimposed upon the interference.The probability density function(PDF)under interference only hypothesis is modified,compared with results from 1.Under the alternative hypothesis,to represent more practical cases,several models of the metric dependent on the backscattering type and spatial dimension of the moving target are discussed 2,and corresponding PDFs ground on these models are derived in closed-form.The derived PDFs provide means to quantify the limits of performance and examine the capabilities of detection,which plays a significant role in system parameter design and algorithm selection
