Problems solved by technology

However, due to the narrow detection range of the nodes and the low accuracy of the initial value estimation when tracking the target, in order to form a continuous, stable and accurate target track estimation, it is necessary to improve the accuracy of track estimation and track fusion through relaying and track fusion between different sensor nodes. stability

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the drawings and embodiments.

[0025] The target model has a body length of 1.304 meters, a height of 0.265 meters, and a wingspan of 2 meters. It is flying at a low altitude of 100 meters; the forward scattering radar has a baseline length of 20km, a transmission power of 40w, a carrier wavelength of 0.3m, and minimum detectable signal noise. The ratio is 10dB; the forward scatter radar network is deployed in a circular area with a radius of 80km. To ensure continuous estimation of the target track, full coverage is used. When the false alarm probability is 10 -8 ~10 -9 When, meet the 90% detection probability.

[0026] A radar network detection method for important ground protection using forward scatter radar. The schematic diagram of radar network deployment implemented by this method is as follows figure 1 As shown, the steps are as follows:

[0027] Step 1: Determine the structure of the basic top...

Abstract

The invention provides a strategic location protection radar network detection method adopting a forward scattering radar, which aims at protecting the safety of the airspace of a strategic location, realizing effective detection of a low-altitude flying small target and forming continuous, stable and precise target track estimation, and belongs to the technical field of radar networking detection. According to the method provided by the invention, the continuous, stable and precise target track estimation is formed and the purpose of protecting the safety of the airspace of the strategic location is achieved by determining a coverage model of the forward scattering radar, selecting a topological structure with optimal topological units based on a genetic algorithm, determining a protection area, comprehensively covering the protection area according to the comprehensive coverage principle and performing target detection, track fusion and other steps.

Description

Technical field [0001] The invention relates to a radar network detection method for important ground protection aimed at low-altitude flying small targets, and belongs to the technical field of radar network detection. Background technique [0002] With the opening of the low-altitude airspace, the safety of the airspace of important sites has been threatened by gliders, model airplanes, kites, remote-controlled aircraft, and UFOs. The safety of important sites has attracted great attention. During the Beijing Olympics, in order to resist various threats from the air, the security department formulated an air defense plan: set up a no-fly zone in a certain range of airspace near important venues; ground radars and even space-orbiting satellites monitor the entire airspace around the clock. [0003] Important ground protection is the main part of homeland protection. In homeland protection, the protection of important areas or targets is called essential protection. It includes t...
