System for testing isolation of guide head of laser terminal guided projectile

Abstract

The invention relates to a system for testing isolation of a guide head, which is used for testing the isolation of the guide head of a laser terminal guided projectile and comprises a signal simulation part, a motion simulation part and a testing main control part, wherein the signal simulation part comprises a laser target simulator, a two-dimensional swing mirror and a reflection screen and is used for generating laser capable of being received by the guide head; the motion simulation part comprises a three-axis turntable capable of loading the guide head and is used for simulating the posture motion of a projectile body; the testing main control part is used for controlling a turntable body to simulate the posture motion of the projectile body according to a predetermined mathematical model, and receiving test data returned from the guide head, so that isolation performance analysis is carried out, wherein laser generated by the laser target simulator is projected on the reflection screen through the two-dimensional swing mirror; furthermore, the guide head receives laser reflected by the reflection screen. Because laser is prevented from being directly projected on the guide head, accurate and effective experimental data about the isolation test of the guide head can be obtained by operators; simultaneously, a real weapon system campaign mode can be well simulated.

Description

technical field [0001] The invention relates to a laser terminal-guided projectile, and particularly discloses a test system for the isolation degree of a seeker of a laser terminal-guided projectile. Background technique [0002] Before the laser terminal guided projectile is launched, the target is irradiated by a laser irradiator about several kilometers in front of the target. Such shells spin at a certain angular velocity throughout their flight. After the projectile is launched, it is first boosted to climb to the highest point. After reaching the highest point of the ballistic trajectory, it begins to slide and then begins the inertial navigation section. At this time, the trajectory and the horizontal line form a certain angle. When the laser signal is returned, the seeker arm is unlocked and begins to track the target. Therefore, the entire ballistic trajectory can be divided into the booster section, the climbing section, the inertial guidance section, and the te...

Problems solved by technology

In other words, the strength of laser energy and the size of the spot are not easy to control. The laser generated by the laser target simulator is directly irradiated on the seeker. Due to the limitation of distance, the high-intensity laser makes the seeker easy to destroy.
