A Multipurpose Radar Antenna System

Abstract

The invention discloses a multi-purpose radar antenna system, which comprises a plurality of antenna units, some antenna units are transmitting multiplexing antenna units, which are used as transmitting antenna units in radar antenna systems in different states; some antenna units are transmitting and receiving multiplexing The antenna unit is used as a transmitting antenna unit or a receiving antenna unit in the radar antenna system in different states; when the radar antenna system is in the unfolded state, multiple antenna units form a single transmitting array element or a single receiving array element, and multiple transmitting arrays The antenna unit and multiple receiving array elements constitute the receiving and transmitting antenna array element of the area array structure for long-distance high-resolution reconnaissance; when the radar antenna system is in the folded state, one antenna unit constitutes a single transmitting The array element and multiple receiving array elements constitute the transceiver antenna array element for close-range high-precision imaging reconnaissance. The invention has the advantages of simple structure, easy operation, adjustable structure and suitable for long- and short-distance reconnaissance.

Description

technical field [0001] The invention mainly relates to the technical field of radar, in particular to a multipurpose radar antenna system. Background technique [0002] Radar is generally composed of modules such as a transmitter, a receiver, a data acquisition and signal processing platform, a transmitting antenna array, and a receiving antenna array. According to the different tasks of the radar, the data acquisition and signal processing platform, transmitting antenna array, and receiving antenna array modules are generally different. Taking wall-penetrating radar as an example, long-distance wall-penetrating radar generally adopts a linear array structure with a large azimuth aperture to achieve high angle measurement accuracy and resolution. The transceiver antenna unit is generally high-gain, narrow beam (multiple Realized by a small array), in order to control the angle coverage, maximize the detection distance, etc., the data acquisition and signal processing platfo...

Problems solved by technology

Due to the different purposes of the above two radars, the array topology, configuration, and structure of the two radars cannot be reused. They need to be implemented with different radar models, which brings certain transportation, storage, and operation to the execution of reconnaissance missions. workload, and at the same time, more guarantees are needed in terms of staffing
