To address the challenge of achieving high target acquisition probability for radar-guided air-to-ground missiles against ground targets
a design method for an airborne forward-squint imaging guidance system with a preset forward-tilt angle is proposed.The overall configuration of the airborne air-to-ground missile forward-squint imaging guidance system is established
and the parameters of the imaging guidance system under multiple constraints are designed according to the characteristics of the missile body.A three-channel guidance and control system is designed
upon which a missile flight trajectory imaged in the seeker spotlight mode at a preset forward-tilt angle is constructed.Subsequently
the system-related parameters are analyzed and evaluated to verify compliance with the constraints of the imaging guidance system.Finally
the backward projection algorithm is employed for imaging processing
and the focusing results validate the effectiveness of the system design.The proposed design method for the imaging guidance system can provide technical support for precision strikes of radar-guided air-to-ground missiles.
