摘要
Abstract
With the wide application of spaceborne synthetic aperture radar （SAR） in military and civilian fields, the countermeasure to spaceborne SAR became increasingly important. On the basis of the analysis of radar sitnal and operating mode,the geometric space model of spaceborne SAR is given, the search domain of viewing center coordinates or viewing angle is built and divided, and the theoretical received power array corresponding to the search domain is calculated in this paper. Furthermore, the sum of power deviation squares between theoretical data and actual data is calculated. After the minimum value searching and iteration, the observation area and operation mode could be calculated more accurately. Simulation results prove the correctness and effectiveness of the algorithm.关键词
