Multipurpose radar antenna system

Abstract

The invention discloses a multipurpose radar antenna system which comprises a plurality of antenna units, and part of the antenna units are transmitting multiplexing antenna units and are used as transmitting antenna units in radar antenna systems in different states. Part of the antenna units are transceiving multiplexing antenna units and are used as transmitting antenna units or receiving antenna units in radar antenna systems in different states. When the radar antenna system is in an unfolded state, a plurality of antenna units form a single transmitting array element or a single receiving array element, and a plurality of transmitting array elements and a plurality of receiving array elements form a transmitting-receiving antenna array element of an area array structure so as to carry out long-distance high-resolution reconnaissance; when the radar antenna system is in a folded state, one antenna unit forms a single transmitting array element or a single receiving array element, and a plurality of transmitting array elements and a plurality of receiving array elements form a transmitting and receiving antenna array element to perform close-range high-precision imaging reconnaissance. The system has the advantages of being simple in structure, easy and convenient to operate, adjustable in framework and suitable for long-distance and short-distance reconnaissance and the like.

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
