Abstract

The invention discloses a sensing system adaptive receiving method based on digital channelization instantaneous parameter measurement. The method comprises the steps that 1), a display control subsystem configures sensing receiving channel parameters and controls realization of an instantaneous adaptive sensing mode; 2), an external electromagnetic environment and signals are injected into a comprehensive radio frequency subsystem through utilization of a radio frequency interface; 3), radio frequency signals are amplified and filtered to obtain intermediate frequency signals, and the intermediate frequency signals are sent to a sensing processing subsystem; 4), an FPGA module of the sensing processing subsystem caches received signals, processes the received signals, and sends a processing result to the display control subsystem; and 5), the display control subsystem receives the processing result, judges the processing result and outputs a judgment result. According to the method, high intercept probability and high sensitivity adaptive sensing and receiving of radar and communication signals in a wide instantaneous bandwidth range can be realized, so the problem that conventional broadband sensing receiver equipment is huge and is high in power consumption and cost can be offset to a relatively great extent.

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...
