Embodiment 1

[0022] combined with figure 1 As shown, a laser seeker dynamic performance automatic test system for terminal guided missiles consists of a real-time simulation computer, a five-axis turntable, tooling 1, tooling 2, a laser target simulator, a laser program controller, a test cable, a connecting cable 1, It consists of connecting cable 2, optical fiber and the test product, namely the laser seeker.

[0023] The five-axis turntable includes a control cabinet, a two-axis target turntable body and a three-axis simulation turntable body. The three-axis simulation turntable body is nested inside the two-axis target turntable body, and the two-axis target turntable body is a vertical U-U upside-down structure, in which the outer axis of the turntable is the yaw axis, the inner axis is the pitch axis, and the yaw axis system The base is connected with the bracket. The three-axis simulation turntable body adopts a vertical U-O-O structure, in which the outer axis of the turntable is...

Embodiment 2

[0046] A method for automatically testing the dynamic performance of a laser seeker for terminally guided missiles, comprising:

[0047]Step S100: Real-time simulation computer runs the test items in the automatic test program, calculates the relative motion position of the laser seeker and the laser target simulator, and sends the turntable information to the control cabinet of the five-axis turntable, and at the same time sends the program control information to Laser programmer;

[0048] Step S200: The control cabinet of the five-axis turntable drives the center coaxial three-axis simulation turntable body and the two-axis target turntable body on the five-axis turntable to rotate according to the received turntable information; the laser program controller controls the laser target simulation according to the received program control information The device generates a laser signal;

[0049] Step S300: the laser seeker receives and tracks the laser signal, and sends the ge...

Abstract

The invention discloses an automatic testing system for the dynamic performance of a laser seeker for a terminal guided missile. The automatic testing system comprises a real-time emulation computer,the laser seeker, a five-axis turntable, a laser target simulator and a laser program controller. The invention further discloses an automatic testing method for the dynamic performance of the laser seeker for the terminal guided missile. The automatic testing method includes the steps that the real-time emulation computer runs a test item, the relative motion position of the laser seeker and thelaser target simulator is calculated, turntable information is sent to a control cabinet, and program control information is sent to the laser program controller; a control cabinet drives a three-axisemulation turntable body and a two-axis target turntable body to rotate; the laser program controller is used for generating a laser signal; the laser seeker receives and tracks the laser signal, andgenerated seeker tracking information is sent back to the real-time emulation computer; and the real-time emulation computer displays and stores testing data. The whole testing system is real-time and can be used for testing the delay characteristic, the tracking characteristic and other dynamic performance relevant to time of the laser seeker.

Description

technical field [0001] The invention relates to the technical field of laser seekers, in particular to the technical field of laser seekers in aerospace technology, in particular to an automatic test system and method for the dynamic performance of laser seekers of terminal guided missiles. Background technique [0002] Lasers are widely used in various fields due to their monochromaticity, good directivity, and small beam divergence. In the aerospace field, the terminal guided missile of the laser seeker is one of the common ones. It has the characteristics of high precision, low cost, high power, easy to use, and it is difficult for the enemy to interfere effectively. It has excellent performance and is favored by countries all over the world. The performance of the laser seeker, especially the dynamic performance, such as noise amplitude, delay time, dynamic tracking effect, etc., directly affects the strike accuracy and combat capability of the guided missile, and is pa...
