Problems solved by technology
In order to improve the detection performance and speed resolution ability of small targets, during the scanning process, the irradiation time of the radar on the target within the beam width of the transmitting antenna is usually increased to increase the accumulated energy of the target, so the rotation speed of the antenna scanning is generally low, resulting in the The rate is limited, which is not conducive to the detection and tracking of high maneuvering UAV targets
Another commonly used system for UAV detection radar is the full phased array system, but the detection airspace of a single array is limited and the cost is high

Embodiment Construction
[0024] In order to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The described embodiment is only one embodiment of the invention, and not all embodiments.
[0025] An embodiment of the present invention provides a multi-area radar system. The antenna array of the system is mainly composed of a three-coordinate area array and a two-coordinate area array. The machine scan mode covers the azimuth-dimensional airspace; each area array has the ability to independently perform target detection and parameter measurement, and can be used as a radar respectively. Each area array has different measurement attributes, among which the three-coordinate area array adopts the elevation single-beam transmission and multi-beam reception system to measure the four parameters of the target's distance, elevation angle, azimuth angle and spee...

The invention provides a multi-area array radar system and a data fusion processing method, which can realize the detection of an unmanned aerial vehicle target and the measurement of position parameters and motion parameters of the unmanned aerial vehicle target and improve the data rate. An antenna array plane of the system is mainly formed by placing a three-coordinate area array and a two-coordinate area array on a same servo base body in a heterogeneous mode, wherein the three-coordinate area array adopts a pitching single-beam transmitting and multi-beam receiving system and is used formeasuring four parameters of a distance, a pitching angle, an azimuth angle and a speed of the target, and the two-coordinate area array adopts an azimuth angle monopulse measuring system and is usedfor measuring three parameters of the distance, the azimuth angle and the speed of the target.
Description
technical field [0001] The invention belongs to the technical field of radar signal processing, and in particular relates to a multi-surface array radar system and a data fusion processing method. Background technique [0002] With the development of UAV technology, low cost and easy availability have popularized the application of UAV equipment, and new application fields are expanding, such as reconnaissance and surveillance, environmental monitoring, disaster relief, aerial photography, etc. Among them, reconnaissance and surveillance are the most widely used fields of drones, which provide great help to the government and the military. However, the frequent occurrence of related incidents such as illegal reconnaissance and monitoring and "black flights" shows that drones pose an increasing threat to public safety. Radar equipment has a long detection distance and stable performance. Using radar to detect drones is an important means of defending against drone threats an...
