Embodiment Construction

[0035] This embodiment provides a multi-source heterogeneous radar cooperative detection method based on a three-dimensional grid. For the problem of multi-source heterogeneous radar cooperative area detection, it evaluates various detection and tracking radars in the area based on a three-dimensional grid, and obtains each Standard Cube Grid A collection of detection radars that meet detection range, angle, and height requirements. Obtain the information of the grid to which the target belongs, and schedule the closest radar in the detection radar set of the grid to detect and track. The three-dimensional grid-based multi-source heterogeneous radar cooperative detection method of the present invention breaks through the limitation of the traditional method mainly targeting the same type of sensors, enhances the cooperation ability between heterogeneous sensors, and can better complete the radiation source target identification task.

[0036] Such as figure 1 As shown, this e...

Abstract

The invention discloses a three dimensional grid-based multi-source heterogeneous radar cooperation detection method. The method is used for solving a problem of detection in a multi-source heterogeneous radar cooperation zone, and all kinds of detecting and tracking radars in the zone are assessed based on three dimensional grids; a set of detecting radars satisfying requirements for detection distance, angles and height in each standard cubic grid is obtained; information of a grid to which an object belongs is obtained; radars, with maximum proximity to the object, in the set of detecting radars in the grid are dispatched for detecting and tracking operation. According to the method, detecting characteristics of different radars are combined, a cooperative detection-based dispatching method is designed, and cooperative detection efficiency is improved.

Description

technical field [0001] The invention relates to radar detection technology, in particular to a multi-source heterogeneous radar cooperative detection method based on a three-dimensional grid. Background technique [0002] With the development of network centralization, collaborative detection of different platforms has become a common trend. The cooperative detection of heterogeneous sensors is a typical cooperative mode (high-precision cooperative estimation method of heterogeneous radar and ESM, Luo Zhifeng, "Computer and Digital Engineering", 2013, 41(8): 1266-1267). The observation data of heterogeneous sensors have different coordinate systems and different attributes. ESM (Electronic Support Measure) has azimuth information and frequency information, but no distance information, while radar has both azimuth information and distance information. Both have their own strengths in detection capabilities: radar has high detection accuracy but a small detection range, whil...
