Searching and scanning control method of photoelectric turret for radar identification target area

Abstract

The invention discloses a searching and scanning control method of a photoelectric turret for a radar identification target area, and belongs to an automatic control technology. The scanning search mode and the search range are automatically calculated according to the view field size of the turret sensor and the target possible range given by the radar, and full-automatic search scanning is achieved. In the area searching and scanning process, the photoelectric turret can switch searching and scanning modes according to the target area range given by the radar and the field angle information range of the current sensor, an appropriate scanning mode is selected from the four scanning modes according to the size of the target area range and the field angle range, and scanning parameters are calculated. Therefore, the whole target area range can be scanned under the condition that the target area changes continuously. Practical tests prove that the searching and scanning control method realizes full-automatic searching and scanning, human intervention is not needed, the target can be found when the range given by the radar is not accurate enough, the efficiency is greatly improved, and the probability of missing the target is reduced.

Description

technical field [0001] The invention belongs to the field of automatic control, and in particular relates to a search and scan control method of a photoelectric turret for a radar identification target area. Background technique [0002] At present, the use of photoelectric turrets and radars to work together is an effective way to achieve day and night search, tracking, surveillance, and identification of air area targets. The photoelectric turret can be aimed at the target area detected by the radar, and detect the contour characteristics and shape information of the target that is difficult to detect by the radar. [0003] However, since the radar gives the range of areas where the target may appear, this range is often not accurate enough. At present, the long-focus field of view of the sensor of the photoelectric turret is very small, and it is difficult to cover the entire target area. It is often impossible to find the target after aligning with the center of the tar...

[0003] However, since the radar gives the area range where the target may appear, this range is often not accurate enough

At present, the long-focus field of view of the sensor of the photoelectric turret is very small, and it is difficult to cover the entire target area. It is often impossible to find the target after aligning with the center of the target area. Therefore, the existing search method is to align the photoelectric turret with the center of the target area. If the target is not found, use the manual search method to continue to manually search for the target in the surrounding area, which is not only low in automation and time-consuming, but also because the target position is changing, it is often difficult to find the target
