基于毫米波InISAR成像的运动目标探测与定位
Moving target detection and location based on millimeter-wave InISAR imaging
摘要
Abstract
An inverse synthetic aperture radar (ISAR) imaging method based on motion compensation of a moving target was presented. The concept of radar imaging was applied to the process of moving target detection with low signal to noise ratio(SNR). The lateral and radial velocity of the target can be acquired by means of imaging processing. The location of the moving target and estimation of its cross-sectional area could be fulfilled using the multi-baseline image in-terferometric method. The geometric model for imaging moving target was established. A method for the compensation of signals from channels of multi- antenna time division multiplexing (TDM) receiver was proposed. The unambiguous angle orientation based on multi-baseline phase unwrapping was presented. The influence of the image SNR on interfero-metric orientation accuracy was analyzed. The validity of the proposed method was testified by both simulation and an example of its application.关键词
