Embodiment Construction

[0037] The working process of the semi-active laser guidance system is that the laser transmitter is installed on the ground, vehicle or aircraft as a signal source, and emits a laser beam to indicate the target for the guided weapon. The laser seeker on the missile receives the laser signal reflected by the target and tracks it. The laser spot that appears on the target guides the warhead to fly to the laser spot and finally hits the target.

[0038] The seeker is equipped with an optical system and a four-quadrant light detection element, which receives the laser energy reflected by the target, and outputs the angular parallax signal representing the line of sight of the target and the speed direction of the guided bomb after processing to form a guidance command, which is sent to the steering gear to rotate Corresponding rudder surface generates control force, thereby correcting flight trajectory.

[0039] Laser seeker laser treatment needs to do the following work:

Abstract

The invention discloses a laser signal solution and servo control integrated processing system. The system comprises an AD converter, a DSP, a DA converter, a power amplifier, a CPLD, a sine signal generation circuit, a gyro mode switching switch and four ways of alternative analog switches; the DSP is responsible for data solution; the CPLD is responsible for working coordination and time sequence control of each module; and the system realizes timing switching and processing of multiple data through the switching switch and the alternative analog switches, so that laser signal solution and servo control work are organically combined to realize a double-function processing system on one board. The system finishes laser signal processing and servo control based on one set of DSP main controllers, so that the system cost is reduced, the hardware resource utilization rate is increased, and the system miniaturization, lightness and reliability are improved.

Description

technical field [0001] The invention belongs to the technical field of laser semi-active seeker guidance control, and in particular relates to an integrated processing system for laser signal calculation and servo control. Background technique [0002] Laser guidance is one of the typical representatives of modern high-tech weapons. Laser semi-active guidance is the most commonly used laser guidance method at present. It has the advantages of high guidance precision, large power, small size, and strong anti-interference ability. To complete the task of attacking the target, the laser precision terminal guided weapon must rely on the automatic seeker to search and track the target to complete the capture, stable tracking and accurate measurement of the target. [0003] At present, the domestic existing technology of semi-active laser guidance seeker is to use two sets of main control chips, a laser signal processing board and a servo control processing board, peripheral hardw...
