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 seeker isolation degree test system of a laser terminal-guided projectile. Background technique [0002] Before the laser terminal-guided projectile is fired, the target is illuminated by a laser illuminator several kilometers in front of the target. These shells spin at an angular velocity throughout their flight. After the projectile is launched, it first assists to climb to the highest point, and when it reaches the highest point of the ballistic trajectory, it starts to slide down and starts the inertial navigation section. At this time, the ballistic trajectory and the horizontal line form a certain angle. When the projectile is close to the target, the seeker can receive the reflection from the target. When the laser signal returns, the seeker unlocks and begins to track the target. Therefore, the entire trajectory can be divided into the boost section, th...

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.
