A Leading Guidance Method Using Multiple Leading Angle Superposition and End Correction

Abstract

The invention relates to a pre-guidance method using multi-lead angle superposition and terminal correction, which belongs to the technical field of aircraft guidance, and is characterized in that firstly, the seeker and gyroscope are used to measure the line-of-sight angle and yaw signal, and secondly, according to the aircraft The flight distance and line-of-sight angle signals intercept the lead angle signal multiple times, and the multiple error signals obtained after comparing multiple lead angles and yaw angles are weighted and synthesized, and then the design of the A special processing link for a large line of sight angle is used to avoid excessive guidance signals at the end. Finally, the above signals are proportionally weighted and integrated to form the final guidance signal, which is output to the aircraft attitude stabilization loop for tracking, and guides the aircraft to accurately fly to the target. This method solves the problem in the prior art that the setting of a single lead angle is difficult to ensure tailing at the end of the guidance, which leads to an excessive amount of miss.

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...

Problems solved by technology

[0005] The purpose of the present invention is to provide a leading guidance method using multi-leading angle superimposition and end correction, and then at least to a certain extent overcome the difficulty in ensuring guidance due to the limitations and defects of the related technology caused by a single leading angle setting. Tail chasing is formed at the end of the lead, which leads to the problem of excessive miss
