Aircraft monopulse avoidance strategy determination method and system

Abstract

The invention relates to an aircraft monopulse avoidance strategy determination method and system. The method comprises the following steps: determining the speed of an aircraft after pulse application; determining the operation angular momentum of the aircraft after the pulse is applied; determining the position of the aircraft after the pulse is applied; determining the eccentricity rate of the aircraft after the pulse is applied; determining a true anomaly of the aircraft after the pulse is applied; calculating an included angle between the initial position of the aircraft and an avoiding position on the avoiding track; determining a semi-major axis of an aircraft orbit after the pulse is applied; determining the spatial distance between the avoiding position of the aircraft on the avoiding orbit and the center of mass of the earth; determining the spatial distance from the position, attacked by an interceptor, of the aircraft to the center of mass of the earth when the pulse is not applied; and carrying out subtraction on the two distances to obtain a distance difference, and determining an optimal avoiding strategy. According to the method, the target aircraft can maneuver according to the preset design parameters when being attacked, and the target aircraft is away from the threat area.

Description

technical field [0001] The invention relates to the field of space attack and defense, in particular to a method and system for determining a single-pulse avoidance strategy of an aircraft. Background technique [0002] With the exploration of space and the development of space technology, the control of the sky becomes more and more important. Space attack and defense has become a hot research topic in the field of space technology and military in various countries. On the other hand, based on the low cost and flexibility of small aircraft, the use of aircraft to intercept aircraft has become the main means of space attack and defense. In the prior art, the research on space attack and defense mainly focuses on using various control methods or intelligent algorithms to optimize the trajectory of the spacecraft, taking energy consumption and flight time as design indicators to achieve the established goals, mostly from the perspective of interception. For the process of at...
