Embodiment 1

[0032] This embodiment provides a cooperative active light-emitting identification marking method, such as figure 1 As shown, the specific steps are as follows:

[0033] S1. The observer uses the target observation equipment to observe the distant target, and the target observation equipment sends out an infrared detection signal through the security check; the infrared detection signal is a pulse sequence signal encoded with pulse position.

[0034] S2. Load the target identification device on the target body, the target body receives the effective infrared detection signal through the target identification device, and judges the source direction of the infrared detection signal, so as to transmit the regular optical identification signal to the direction. Here, the "effective infrared detection signal" refers to the infrared detection signal that conforms to the predetermined coding law of the observer and the target body; henceforth, the "set law" also refers to the predete...

Embodiment 2

[0038] This embodiment provides a cooperative active light-emitting identification system, which is composed of target observation equipment and target identification equipment. The specific design is as follows:

[0039] 1. Target observation equipment, used to emit infrared detection signals and observe optical identification signals; design target observation equipment including infrared telescopes, laser light sources and coding drive boards; infrared telescopes are used to observe optical identification signals; laser light sources are used to emit infrared Detection signal; the encoding driver board is used to complete the encoding and driving of the infrared detection signal.

[0040] Specifically, it can be reformed from existing mature infrared telescopes. The infrared telescope itself has the ability to observe infrared and white light. It can add a laser light source (near-infrared band) and a coding driver board to its hardware. The coding driver board completes th...

Abstract

The invention discloses a collaborative active light-emitting identification method and system. The method comprises the following steps that: an observer emits an infrared detection signal through target observation equipment; a target body receives an effective infrared detection signal through target identification equipment, judges the source orientation of the infrared detection signal, and transmits an optical identification signal with a set rule to the orientation; an observer observes whether the target body radiates the optical identification signal or not through target observation equipment, and judges whether the target body is an own cooperative person or not by judging whether the observed optical identification signal is an optical identification signal with a set rule or not, so that the identification process is completed; and the infrared detection signal is a pulse sequence signal coded by adopting a pulse position. By using the collaborative active light-emitting identification method and system provided by the invention, simple and rapid identification of a moving target can be realized under the condition of certain concealment, the problems of short continuous working time and easy active exposure of an existing identification method are solved, and the equipment can obtain good market benefits.

Description

technical field [0001] The invention relates to the technical field of target recognition, in particular to a cooperative active light-emitting identification mark method and system. Background technique [0002] Target recognition technology is a technology that obtains target information through specific methods for identification. Target recognition technology can be divided into two types: cooperative and non-cooperative according to its working principle: cooperative target recognition mainly detects and recognizes long-distance targets through secondary radar; non-cooperative target recognition mainly uses primary radar (including thermal radar and LiDAR) uses echo / radiation signals to complete the detection and analysis of target features. In addition, active / passive identification marks also belong to the category of non-cooperative target identification, which is characterized by the fact that it does not require the process of radar detection, but uses infrared th...
