Abstract

The invention relates to a CCD laser theodolite dynamic radar calibration method. And the measuring system of the method adopts Laser distance measurer, theodolite, CCD camera, and GPS timing part to complete ship-carried coordinate dynamic calibration, and besides, in the calibration course, applying conversion formula between UTM coordinates and WGS-84 coordinates to ship-carried radar dynamic calibration. And it implements high accuracy measurement, where angular accuracy is 10s, and position accuracy is 0.5m. And it can save lots of man power and material resources; it uses CCD camera to record radar feed state so as to real-timely and afterwards process. And it solves the problem that instrument-carried, shore-based radar calibrators are united.

Description

technical field [0001] The invention belongs to the technical field of radar calibration and relates to a dynamic radar calibration method for a CCD laser theodolite. Background technique [0002] The measurement of the target by the radar is a relative measurement, and the absolute position of the target can only be measured if the absolute position of the radar and the measurement reference of the azimuth and elevation angle of the radar are known. The zero error of radar is an important technical index in the use of radar. If the zero error of radar exceeds the design index requirements, it will directly affect the positioning accuracy of radar, the accuracy of fire control system and the hit probability of tactical missiles. Therefore, radar zero calibration is a very important technical work. Radar calibration generally requires the radar to meet certain ideal conditions: [0003] (1) The radar carrier and target are both in a static state. [0004] (2) The radar car...
