Abstract

The invention discloses a multi-broadband radar system capable of quickly distinguishing target sorties, which belongs to the technical field of radars and comprises an antenna module, a transceiving module, a waveform generation module and a signal processing module, and the antenna module, the waveform generation module and the signal processing module are in communication connection with the transceiving module. On the basis of a traditional radar system design, waveforms with various bandwidths are generated according to a radar control command, power amplification, radiation and receiving are completed through the receiving and transmitting module and the antenna module, processing such as beam forming, pulse compression and filtering of echo signals and extraction and output of data are completed through the signal processing module. Radar normal detection and target sortie resolution requirements are met, and the system is worthy of popularization and application.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to a multi-bandwidth radar system capable of rapidly distinguishing target sorties. Background technique [0002] Most of the current radar systems are designed with one signal bandwidth. Radar with a single bandwidth can only transmit a signal with one bandwidth. The wider the bandwidth, the finer the distance resolution of the target, but the greater the amount of data that needs to be processed, so In order to meet the requirements of communication capacity and processing capability, most radars are narrow-band radars, and the radars only emit a narrow-band signal to meet the detection requirements of radars; some radars are designed with two bandwidths and time-sharing in order to take into account the processing requirements and high-range resolution functions Work, generally using narrowband work, when it is uncertain that a certain batch of targets is flying in multiple target ...
