Photoelectric detection radar and detection method thereof

Abstract

The invention relates to the technical field of infrared imaging, and discloses a photoelectric detection radar and a detection method thereof, and the photoelectric detection radar comprises a thermal imager assembly which is used for obtaining an infrared image of a to-be-detected scene, and transmitting a digital image signal of the infrared image to a real-time information processor; a photoelectric turntable which is used for receiving a search instruction from the real-time information processor and adjusting the window angle of the thermal imager assembly according to the search instruction so as to perform panoramic search; a controller which is also used for receiving a tracking instruction from the real-time information processor and adjusting the thermal imager assembly according to the tracking instruction to realize closed-loop tracking of the target; a real-time information processor which is used for generating a search instruction and is also used for receiving the digital image signal, carrying out target detection processing on the digital image signal to extract target position information of the target, generating a tracking instruction according to the target position information, and sending the tracking instruction to the photoelectric turntable. And wide-area detection and accurate tracking of birds in the aviation industry can be realized.

Description

technical field [0001] The invention relates to the technical field of infrared imaging, in particular to a photoelectric detection radar and a detection method thereof. Background technique [0002] At present, with the rapid development of the aviation industry, bird strike accidents often occur on flights and aircraft. Bird strike incidents not only cause huge economic losses, but also seriously threaten the lives of flight attendants. They have been designated as Class A aviation disasters by the International Aviation Federation. [0003] For the prevention of bird strikes, the current manual observation of bird activities with naked eyes or binoculars is still the main method. This method has limited monitoring range, low efficiency, and is easily affected by day and night and weather conditions, which has great limitations. In addition, some airports use directional sonic cannons or lasers to drive away birds on aircraft routes at fixed points. This method lacks prior...

Problems solved by technology

[0003] For the prevention of bird strikes, the current method of observing bird activities with the naked eye or binoculars is still the main method. This method has limited monitoring range, low efficiency and is easily affected by day and night and weather conditions, which has great limitations.

In addition, some airports use directional sonic cannons or lasers to drive away birds on the aircraft route at fixed points. This method lacks prior information on the flight trajectories of birds, and the scope of the airspace is still limited, and the effect is not ideal.

There are also airports that use visible light and infrared sensors for video surveillance, while carrying gimbals to track birds. Due to the limited tracking accuracy and real-time processing capabilities of gimbals, it is difficult to achieve stable tracking of birds flying with high maneuverability, let alone Further obtain the target feature information required for identification

In some developed areas, radar is used as an important means of detecting bird activities. This method can monitor and warn birds around the airport in a large range and at a long distance, but the disadvantage is that active detection can easily interfere with the electromagnetic environment of the airport; It is seriously interfered by ground clutter; it is impossible to automatically identify and confirm the target; the equipment is complex and huge, and the cost is high
