Multifunctional phased array radar device and detection method thereof

Abstract

The invention relates to a multifunctional phased array radar device. The multifunctional phased array radar device includes an antenna feeder extension, a transceiver extension, a frequency synthesisand system monitoring extension, an integrated signal and information processing extension, an integrated display and control extension and a power extension, wherein the antenna feeder extension includes a radar array surface and an antenna network, the antenna feeder extension completes radiation and reception of an electromagnetic wave signal, the transceiver extension performs digital-to-analog conversion and up and down conversion of the electromagnetic signal, the frequency synthesis and system monitoring extension generates an excitation signal, a system clock and a local oscillator and performs system monitoring, the integrated signal and information processing extension completes beamforming, radar signal processing and data processing, the integrated display and control extension is for human-computer interaction and information display, and the power extension provides the DC power. The multifunctional phased array radar device is advantaged in that through primary radar and secondary radar data fusion, the real-time information of all air targets can be acquired, target comprehensive information messages and the comprehensive situation information are formed, and display and report of the comprehensive information are further performed.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a multifunctional phased array radar device and a detection method thereof. Background technique [0002] With the rapid development of my country's economy and the opening of low-altitude airspace, my country's civil aviation, general aviation and UAV industries have developed rapidly, and a large number of civil aviation airliners, general aviation aircraft and low-altitude UAVs have increased every year. However, the corresponding airspace awareness and airspace management capabilities are seriously insufficient, which seriously hinders the improvement of airspace utilization efficiency, poses a serious threat to airspace flight safety, and seriously lags behind the development of the industry. [0003] In 1994, a Boeing 747 at London's Heathrow Airport crashed after colliding with a flock of pigeons, killing all 350 people on board. In 2000, a wild swan was sucked into...

AI Technical Summary

Problems solved by technology

In May 2017, at Shuangliu Airport, drones were found many times, threatening the normal flight of passenger planes and causing delays of many flights

In February 2018, an oil-electric hybrid UAV flew illegally in Tangshan City, Hebei Province, causing huge losses to the military and civil aviation

[0005] At present, general-purpose equipment cannot balance the detection and monitoring performance of flying targets, and has the disadvantages of poor environmental adaptability, low target detection accuracy, low search data rate, small target capacity, weak target tracking ability, insufficient monitoring capability, high cost and few functions.

Ning Huansheng and others proposed a bird detection device based on primary radar [Ning Huansheng; Chen Weishi; Liu Wenming; Song Jianmin. Mobile radar bird detection device], which can only detect flying targets in two dimensions and cannot monitor cooperative targets

Sun Xiaobo proposed a large field of view low-light low-altitude UAV detection device [Sun Xiaobo. A large field of view low-light low-altitude UAV detection device], the detection distance of the flying target is short, the environmental adaptability is weak, and the cooperative target cannot be monitored

Zhou Lei and others proposed a mobile air traffic control secondary radar [Zhou Lei; Man Yuegang; Jin Xiaofei; Li Cheng; Ding Fei. Mobile large air traffic control secondary radar], which can detect cooperative flight targets with on-board transponders Surveillance, but no detection of non-cooperative flying targets

Existing radar devices lack the ability to detect non-cooperative targets and monitor cooperative targets at the same time, and the acquired target information is less, with low accuracy, and cannot form complete airspace target situation information
