Novel lead guiding method adopting multi-lead-angle superposition and end correction

Abstract

The invention relates to a novel lead guiding method adopting multi-lead-angle superposition and end correction, and belongs to the technical field of aircraft guidance. The novel lead guiding methodadopting multi-lead-angle superposition and end correction is characterized in that a sight-angle signal and a yaw signal are measured through a guiding head and a gyroscope; then, lead angle signalsare intercepted multiple times according to the flight distance of an aircraft and the sight-angle signal, and the multiple lead angle signals are compared with a yaw angle to obtain a plurality of error signals for weight integration; afterwards, a large-sight-angle special processing link is designed for the condition that the sight angle of the tail section of the aircraft is excessively large,so that a guide signal of the tail section is prevented from being too large; and finally, the signals are subjected to proportional weight integration and are integrated to form a final guide signalwhich is output to an aircraft attitude stabilization circuit for tracking, and then the aircraft is guided to accurately fly towards a target. By the adoption of the novel lead guiding method, the problem that the setting of a single lead angle in the prior art cannot guarantee tracking of the tail section of the aircraft, and consequentially, a large target-missing rate is caused is solved.

Description

technical field [0001] The invention belongs to the field of aircraft guidance and control, and in particular relates to a high-precision leading guidance control method using multiple leading angle superpositions. Background technique [0002] With the rapid development of computer technology, the method of using multiple lead angles in the field of aircraft guidance can be realized completely. The physical meaning of the traditional single lead angle is relatively clear, so it is widely used in the steering algorithm. However, compared with the multi-lead angle guidance of the present invention, the single lead angle is obviously less error-tolerant. Moreover, the physical meaning of multi-lead angle guidance is more clear, especially during the flight, according to the change of the target's movement situation, the information of the lead angle can be continuously modulated, so that the strike accuracy is higher, the flight trajectory is more reasonable, and the guidance...
