Abstract

The invention relates to a wideband integrated reconnaissance receiver, which comprises an analog channelized module and a digital channelized module, wherein the analog channelized module further comprises a four-way power divider, bandpass filters from a first to a fourth, two-way power dividers from a first to a fourth, detectors from a first to a fourth, delay modules from a first to a fourth, an acquisition analysis module, a four-point source module, a 4-1 microwave switch module and a mixing module; and the digital channelized module further comprises an AD conversion module, a multi-phase filter module, an FFT calculation module, a threshold detection module, a frequency calculation module and a data storage module. The reconnaissance receiver thoroughly merges features of a direct detection-type receiver, a superheterodyne receiver and a digital channelized receiver, the quick response ability of the receiver and the adaptability to a complex electromagnetic environment are increased, and the adaptability to the complex electromagnetic environment and the reconnaissance real-time performance are met.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a broadband integrated reconnaissance receiver and a working method thereof. Background technique [0002] At present, most guidance radars use a multifunctional phased array system, using LPI signal form, inter-pulse frequency agility, multi-pulse accumulation processing, and intra-pulse using linear frequency modulation, nonlinear frequency modulation or frequency-phase coding waveforms to obtain the required range resolution. With the increasingly complex electromagnetic environment, in order to realize broadband electromagnetic environment signal perception and fast response capabilities, the electronic reconnaissance receiver technology has put forward higher and higher requirements. Contents of the invention [0003] In view of the above analysis, the present invention aims to provide a broadband integrated reconnaissance receiver and its working method, w...
