Abstract

The invention relates to a radar system, specifically to a three-coordinate low-altitude small target radar. The three-coordinate low-altitude small target radar comprises an antenna feeder subsystem, a receiving subsystem, a signal processing subsystem, a wave beam control subsystem, a rotary table servo subsystem, a terminal subsystem and a power supply subsystem, a four-channel T / R module adopts a distributed T / R component, and the component adopts highly integrated design and has the advantages of light weight, small size, good consistency, excellent technical indexes and the like. The three-coordinate low-altitude small target radar provided by the invention can realize search and tracking of an aerodynamic target such as a small airplane, a paraglider and an unmanned aerial vehicle in a low-altitude airspace in a range with a central radius of 45km, precisely monitor the target in the low-altitude area which is low in height, slow in speed and small in size, display and output distance, direction, speed and height information of the flight target, and form a three-coordinate motion situation of the low-altitude target.

Description

technical field [0001] The invention relates to a radar system, in particular to a three-coordinate low-altitude small target radar. Background technique [0002] Phased array radar is a phase-controlled electronically scanned array radar. It uses a large number of individually controlled small antenna elements to form an antenna array. Each antenna element is controlled by an independent switch. Based on the Huygens principle, it controls the time difference of each antenna element's emission. , the main beams of different phases (directions) can be synthesized, and the phase changes can be performed in both axes; similar to Thomas Young's double-slit experiment, the electromagnetic waves emitted by each phase shifter of the phased array interfere constructively The principle strengthens and synthesizes a nearly straight radar main lobe, while the side lobes are greatly reduced due to interference cancellation. [0003] The beam scanning of ordinary radars relies on the ro...
