Problems solved by technology

[0003] At present, in the existing guidance system based on hardware-in-the-loop simulation technology, the seeker simulation part and the target simulation simulation part each constitute a separate turntable, which is expensive, and each part is large in size and complex in structure, and the simulation process is relatively complicated. More noise, less precision

Abstract

A missile guidance system semi-physical simulation method of the invention includes the following steps: (1) a missile-target engagement mathematical model, a target simulator motor speed control model and a CCD camera motor speed control model are established in a host machine; (2) TCP / IP communication between the host machine and a target machine is established, and the TCP / IP communication is compiled to the target machine; (3) a CCD camera is powered on, and an image of an area where a target simulator is located is taken; (4) the image is transmitted to a target tracking experimental turntable control box; (5) a target is identified; (6) an operator uses a rocker to lock the target, and outputs the misalignment angle of a missile seeker to the target machine; (7) the process in whichthe missile seeker tracks the target is simulated; (8) the angular position and angular velocity information of the motor and the line-of-sight angular velocity are obtained; (9) key data in the simulation process is monitored in real time through the display of the target machine; and (10) the target machine feeds back the calculation result through a TCP / IP mode to the host machine for subsequent data analysis.

Description

technical field [0001] The invention relates to a semi-physical simulation method of a missile guidance system, in particular to a semi-physical simulation method of a TV-guided missile. It belongs to the field of aerospace simulation. Background technique [0002] Hardware-in-the-loop simulation is the process of combining mathematical models with physical models or physical models for experiments. Half-physical simulation establishes a mathematical model for the relatively simple part of the system or the part whose law is relatively clear, and realizes it on the computer; for the more complex part or the part whose law is not clear, directly use the physical model or kind. [0003] At present, in the existing guidance system based on hardware-in-the-loop simulation technology, the seeker simulation part and the target simulation simulation part each constitute a separate turntable, which is expensive, and each part is large in size and complex in structure, and the simu...
