To improve the slow and small target detection performance of current interferometric SAR (INSAR), a new method is explored to implement constant false alarm rate (CFAR) detection for full polarimetric along-track INSAR (AT-POLINSAR). First, by designing a single-baseline AT-POLINSAR, we point out its feasibility under current technology conditions and analyze its signal form as well as polarimetric interferometric echo. Second, a new dimension reduction method for AT-POLINSAR 6D polarimetric interferometric vector is proposed using the background clutter average coherence as optimization criterion, from which the scalar echo in suboptimal polarization that has the same distribution type with single polarization can be obtained, and then the traditional single polarimetric INSAR slow target detector can be extended to be full polarimetric. Finally, Monte Carlo experiments and AT-POLINSAR scene detection experiments are carried out to compare the slow target detection performance of suboptimal polarimetric detectors and single polarimetric ones. The results indicate that suboptimal polarization can make full use of full polarimetric information to improve the INSAR detection probability of slow and small target.
