Embodiment Construction
[0021] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0022] The present invention provides a minimum overload terminal guidance method with fall angle constraints, since the position information of the target is known, the real-time position, velocity, trajectory inclination and trajectory angle information of the missile can be guided by the SINS / GNSS combination on the missile The real-time measurement of the system is obtained. Firstly, according to the information of the relative position between the missile and the target point after turning into the terminal guidance, it is proposed to use a ballistic trajectory with a combination of arc and straight line for the ideal system (that is, the system without the lagging link of the autopilot). The characteristic guidance law realizes the large drop angle and high-precision guidance of the missile to the stationary target; then considering the hysteresis lin...
