Heterogeneous aircraft cooperative guidance method considering attack time and attack angle constraints

Abstract

The invention provides a heterogeneous aircraft cooperative guidance method considering attack time and attack angle constraints. The method comprises the following steps of S1, establishing aircraftmathematical models and a relative motion relationship; S2, designing a specified time hit guidance law for a main aircraft; and S3, designing guidance laws for slave aircrafts, wherein the aircraft group is composed of a single main aircraft and a plurality of slave aircrafts, and only the main aircraft can receive an attack time instruction. According to the method, firstly, the mathematical models of the main aircraft and the slave aircrafts are established, a motion relationship between the main aircraft and the slave aircrafts relative to a target is given, and the guide law for hitting the target at a specified moment for the main aircraft is designed on the basis; and in order to ensure that the slave aircrafts and the main aircraft hit the target at the same time, a cooperative guidance law is designed to enable the distance between the slave aircrafts and the target to be consistent with the distance between the master aircraft and the target, and the sight angle of the slaveaircrafts relative to the target tends to a preset expected angle.

Description

technical field [0001] The invention relates to a cooperative guidance method for heterogeneous aircrafts considering attack time and attack angle constraints, which belongs to the field of aircraft guidance and control, and specifically designs a cooperative guidance strategy to realize that the entire group of heterogeneous aircrafts hits a target at a specified time at the same time. Background technique [0002] In military operations, high-value targets are usually protected by defense systems. Therefore, using a single aircraft to independently guide such targets is easily intercepted by the defense system, and the combat success rate is low. Multi-aircraft cooperative guidance is regarded as one of the effective ways to break through the defense system to strike targets, and it is an important direction to realize the transformation from a "platform-centric" single aircraft combat method to a "network-centric" multi-aircraft combat method. Through coordinated operatio...

Problems solved by technology

[0003] However, most of the existing cooperative guidance methods focus on the design of homogeneous aircraft groups, and there is still little research on the cooperative guidance methods for heterogeneous aircraft

In addition, for multiple aircraft to attack targets at designated time, the existing guidance method is to assign the same attack time command to each aircraft, requiring each aircraft to have the ability to receive attack commands, and there is no information interaction between aircraft, the guidance law Independent design, so the ability of information sharing and coordination is weak
