Problems solved by technology

[0002] The traditional reconnaissance system can only conduct reconnaissance for a single frequency band, and cannot meet the needs of full-band broadband reconnaissance
At present, the receiving and processing device mainly adopts a narrow-band fast scanning receiving system, which has high receiving sensitivity, equipment tends to be miniaturized, and has relatively low requirements for the processing speed of intermediate frequency digitization, but its interception probability is low and its real-time performance is poor. Facing complex electromagnetic environments, inability to perceive in time

Description

technical field [0001] The invention relates to a wideband parallel receiving and processing device based on VPX bus, belonging to the technical field of signal reconnaissance and direction finding. Background technique [0002] The traditional reconnaissance system can only carry out reconnaissance for a single frequency band, and cannot meet the needs of full-band broadband reconnaissance. At present, the receiving and processing device mainly adopts the narrow-band fast scanning receiving system, which has high receiving sensitivity, the equipment tends to be miniaturized, and the requirements for the intermediate frequency digital processing speed are relatively low, but its interception probability is low and the real-time performance is poor. Facing the complex electromagnetic environment, Unable to perceive in time. [0003] Based on the above conditions, the target reconnaissance system needs to be designed based on a multi-channel broadband parallel receiving syste...
