摘要: 该文建立了发射站固定的双站合成孔径声纳模型,并对其分辨特性等原理进行了分析和研究,得到了距离分辨力 、脉冲重复频率以及测绘速率严格的数学解,同时给出了有关计算机仿真。仿真结果验证了理论分析的正确性,表明了双站合成孔径声纳成像方法可行、有效。Abstract: Firstly, a Bistatic Synthetic Aperture Sonar (Bi-SAS) configuration with fixed transmitter is given in this paper, and then the azimuth and range resolution, the Pulse Repetition Frequency (PRF) and the mapping rate of the Bistatic-SAS are studied in detail. The analytical solutions are obtained, consequently, the computer simulation are presented in the end. The simulation results validate the correctness of the theory and show the validity of the method in the Bistatic-SAS image.
