Experimental Demonstration of the ABMP Mode Using the N-SAR Data

Abstract

The Alternating Bistatic Multi-Polarized mode (ABMP mode) is a new airborne SAR/InSAR operational mode which combines the polarimetric mode and the alternating bistatic mode. The pulse repetition frequency (PRF) of the ABMP mode is four times than the need of monostatic single-polarized mode based on two transmit-receive SAR radars of N-SAR (SAR of Nanjing Research Institute of Electronic Technology) system. In this paper, we show the experimental results to validate the efficiency of the ABMP mode. By using the ABMP mode, the monostatic and bistatic polarimetric SAR images can be simultaneously collected. Hence, we mainly demonstrate the monostatic and bistatic SAR, SAR interferometry (InSAR) and polarimetric SAR interferometry (Pol-InSAR) using N-SAR data acquired by the ABMP mode. We also firstly demonstrate the preliminary result of TomoSAR using N-SAR data. Moreover, the main test site lies in Shanxi province in the northwest of China
