Abstract

The invention discloses a seeker aiming and positioning method and an aiming and positioning system, wherein the method comprises: sending laser light through the optical window of the seeker into the optical system; receiving the cat's eye echo signal returned by the optical system, After the axial compression unit compresses the field of view, it enters the photodetection imaging unit for imaging and outputs to the signal processing unit; wherein, by controlling the working sequence of the laser and the photodetection imaging unit, the original images of two adjacent frames formed by the photodetection imaging unit Corresponding to the emission state and non-emission state of the laser, respectively, to obtain the difference image of two adjacent frames, and output it to the signal processing unit; the signal processing unit uses the centroid capture algorithm to calculate the difference image, and obtains the gray value centroid of the difference image position, output target information. The present invention has a compact overall structure, and can output target position information whose accuracy is higher than that of a single pixel by improving the working mode and calculation method.

Description

technical field

[0001] The invention relates to the technical field of photoelectric aiming and positioning systems, in particular to a seeker aiming and positioning method and an aiming and positioning system. Background technique

[0002] At present, the main targets of airborne electro-optical countermeasure equipment are air-to-air guided missiles. This type of guided missile is mainly based on the optical guidance method. When the guided missile is launched and locked on our flying target, the field of view of its optical system is facing our target. The working method of the airborne electro-optical countermeasure equipment is to lock the guided missile during the flight phase. When the aircraft infrared warning system detects the incoming target and gives the approximate position of the target, the airborne electro-optical countermeasure equipment is transferred to the position of the target, and then the target Carry out high-precision capture and tracking, and at t...
