Embodiment Construction

[0021] The present invention is further described below by specific embodiment:

[0022] Refer to attached figure 1 , rotating multi-sensor photoelectric radar see figure 1 , where A and B are radar array elements, and its structure includes two parts: the photoelectric detection subsystem and the search and tracking subsystem, such as figure 2 Its basic functions are divided into two parts: 1) Search and track: each radar array element can independently complete the function of searching and capturing targets. 2) Tracking measurement: Each radar array element independently completes the tracking and angle measurement of the reconnaissance target.

[0023] The information parameters obtained from the target detection by the two radar array elements are transmitted to the processing and display subsystem C, and the processing and display subsystem C calculates the target position parameters by using the double-station intersection method.

[0024] In this embodiment, the ...

Abstract

The invention discloses a photoelectric detection device of a rotary multi-sensor photoelectric detection radar. A servo rotating system similar to the radar can be used for carrying out 360-degree continuous rotation scanning or carrying out fan scanning on a specific airspace. The invention does not emit any electromagnetic waves, an array formed by a passive photoelectric sensor-low-light CCD (covering visible light and near infrared rays) and a thermal infrared imager (in the middle-infrared band of 3 to 5 micrometers) in the refrigeration is adopted for realizing 24-hour searching and detection on objectives in the air or on the ground, after moving objectives are found, two tracking and identification units are used for carrying out continuous tracking on the objectives and identifying the objectives according to the shapes of the objectives, and various factors such as the position, the altitude, the distance, the speed and the like of the objectives are calculated in a method of combining double-station crossed positioning and three-dimensional image distance measurement. The rotary multi-sensor photoelectric radar becomes the photoelectric radar with all functions of the radar.

Description

technical field [0001] The invention belongs to the technical field of photoelectric detection and relates to a photoelectric radar. Background technique [0002] At present, military technology is developing rapidly in the world, especially foreign stealth aircraft, low-altitude cruise missiles and unmanned aircraft have reached the stage of actual combat application. At present, our country mainly relies on radar to complete its detection. With stealth design, RCS and optical cross-section are small, making it difficult to detect with radar. At the same time, it is more difficult for radars to find targets in a complex electromagnetic environment (including the electromagnetic interference implemented by the target itself). Conventional radars have poor concealment of electromagnetic waves emitted to the outside, are vulnerable to anti-radiation weapons in wartime, and have low battlefield survivability. Therefore, the air defense situation in our country is becoming incr...
