Abstract

The invention relates to a phased array radar multi-domain agile anti-interference method, relates to the technical field of radars, in particular to a phased array radar multi-domain agile anti-interference method which comprises the following steps: firstly, acquiring related information of interference by using a reconnaissance channel of a radar, then, carrying out full agile scanning according to a beam scanning area, adopting a frequency agile mode during radar scanning, and then, working at each beam position by adopting frequency agile and waveform agile, wherein the working parameters can also be subjected to parameter agility, and finally storing real waveforms and parameters and using as transmitting signals and receiving matching signals of the radar; anti-interference is carried out in a multi-domain agility mode of the spatial domain, the frequency domain, the waveform domain, the parameter domain and the like, the capability of simultaneously inhibiting composite interference such as cheating and suppressing is achieved, the defects that a radar working mode and signals are prone to reconnaissance interference are overcome, and the advantages of resisting multi-style composite interference and being large in interference number are achieved. The method can be used for various phased array radar systems, is easy to implement and has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to a multi-domain agility anti-jamming method for phased array radar. Background technique [0002] As an important direction of modern radar development, phased array radar has been widely used in both military and civilian fields. Compared with mechanical scanning radar, phased array radar has many advantages such as dexterous pointing and reconfigurability, and it is easy to realize multi-beam and multi-function, so it has broad application prospects. [0003] However, with the rapid development of modern electronic technology, the jamming technology for phased array radar is also developing rapidly. Through some confrontation examples in recent years, it can be seen that some shortcomings of phased array radar have also begun to be exposed. The multi-channel characteristic of phased radar makes it have good ability to resist side lobe interference, but the main lobe interference...
