Abstract:

Existing terminal guidance technologies in monostatic platform cannot distinguish targets efficiently when missile attacks targets against complicated background. As a solution, bistatic forwardlooking synthetic aperture radar (SAR) is applied to diving and attacking period, Missileborne bistatic forward looking synthetic aperture radar (MBFL-SAR) could perform two dimensional (2D) high resolution imaging and passive homing during the whole terminal diving period of missile. The trajectory of irradiating missile acting as transmitter has great influence on imaging resolution of bistatic platform and guidance precision. Firstly, the resolution property of the special configuration in diving period is analysed, and then a design method of trajectory based on a linearly attenuating model is developed. This model can satisfy imaging resolution, and is also propitious to guidance in bistatic platform. Finally, simulation results show the validity of the proposed method.
