Problems solved by technology

On the evening of May 28, 2016, the "Black Fly" drone forced the grounding of 55 flights at Chengdu Shuangliu Airport, which seriously disrupted the flight order at the airport.
Traditional radar real-time signal processing generally adopts the scheme based on microprocessors such as programmable logic device (FPGA) and high-speed digital signal processing device (DSP), which has the advantages of fast processing speed and easy to meet real-time requirements, but it also has the advantages of development Disadvantages such as high difficulty, long cycle, and difficulty in later maintenance or upgrade
Since general single-chip processors cannot meet the needs of high-complexity signal processing, it is often necessary to jointly utilize multi-chip processors for processing, which greatly increases the cost of equipment

Embodiment Construction

[0055] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit this invention.

[0056] In recent years, GPU has become the first choice for low-cost external radiation source radar real-time signal processing solutions due to its extremely high cost performance, powerful floating-point calculation and parallel processing capabilities. Currently, GPU-based general computing programming models mainly include CUDA, OpenCL, DirectCompute, AMD APP and Brook GPU. Among them, CUDA based on C language programming is the most mature general-purpose computing solution with the largest market share. It has the advantages of low cost, simple structu...

Abstract

The invention discloses a passive coherent location radar-based unmanned aerial vehicle real-time monitoring system and method. The system comprises a data receiving unit, a data transmission unit, a real-time signal processing unit and a terminal display and control unit; the data receiving unit is used for receiving reference signals of a transmitting source and monitoring signals reflected by an unmanned aerial vehicle and inputting the signals to the real-time signal processing unit through the data transmission unit; and the data are processed by the real-time signal processing unit, so that the flight path of the unmanned aerial vehicle can be obtained and is displayed in real time on the terminal display and control unit. The passive coherent location radar-based unmanned aerial vehicle real-time monitoring system and method of the invention do not need frequency allocation, generate no electromagnetic pollution and can perform monitoring around the clock. The passive coherent location radar-based unmanned aerial vehicle real-time monitoring system and method have the advantages of high data processing speed, high data update rate, real-time monitoring, low development and maintenance cost and strong networking capacity.

Description

technical field [0001] The invention belongs to the technical field of external radiation source radar, and relates to a real-time monitoring system and real-time signal processing method of an external radiation source radar unmanned aerial vehicle based on digital television signals, which can be designed based on a heterogeneous architecture program under the VC+CUDA software development platform Realize real-time signal processing and real-time monitoring of small drones. Background technique [0002] In recent years, news about drones trespassing on sensitive areas has frequently appeared in the newspapers. Drone intrusion incidents have occurred in important security places such as the White House in the United States, the Blue House in South Korea, and the official residence of the Japanese prime minister. On the evening of May 28, 2016, the "Black Fly" drone forced the grounding of 55 flights at Chengdu Shuangliu Airport, seriously disrupting the flight order at the ...
