Research on Principle of the Bistatic Synthetic Aperture Sonar
双站合成孔径声纳系统原理研究

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.
