Abstract

The invention discloses a reconnaissance system adaptive receiving method based on digital channelized instantaneous parameter measurement. The steps include: 1) the display control subsystem configures the reconnaissance receiving channel parameters, and controls to realize the instantaneous adaptive reconnaissance mode; 2) the external electromagnetic environment and The signal is injected into the integrated radio frequency subsystem through the radio frequency interface; 3) the radio frequency signal is amplified and filtered to obtain an intermediate frequency signal and then sent to the reconnaissance processing subsystem; 4) the FPGA module of the reconnaissance processing subsystem receives the received signal Buffering is performed to process the received signal, and the processing result is sent to the display control subsystem; 5) The display control subsystem performs judgment after receiving the processing result, and outputs the judgment result. The invention can realize high interception probability of radar and communication signals in a large instantaneous bandwidth range, and high sensitivity adaptive reconnaissance reception, so it can largely compensate for the problems of traditional broadband reconnaissance receivers such as bulky equipment, high power consumption, and high cost.

Description

technical field [0001] The invention relates to a measurement method in the field of communication technology, in particular to a reconnaissance system adaptive receiving method based on digital channelization instantaneous parameter measurement. Background technique [0002] The wide application of ultra-wideband radar poses a huge challenge to the traditional signal reconnaissance system. Its methods of reception, signal processing, detection and parameter estimation are quite different from those of narrowband signal processing. high demands. [0003] Ultra-wideband signals not only make electronic reconnaissance may be in a more complex electromagnetic environment, such as negative signal-to-noise ratio, but also have great difficulties in sampling, real-time processing and storage, which greatly reduces the sensitivity of reconnaissance receivers. [0004] Therefore, how to improve the signal-to-noise ratio, thereby improving the detection probability, is very importan...
