The short-wave channel unit comprises amode selection circuit, a first switch, a narrow-band signal processing circuit, a second switch and a universal signal processing circuit. The multi-channel monitoring receiver comprises an antennacombiner, first to Nth short wave channel units, a reference shunt module, a multi-channel sampling module, a receiving processing unit and a monitoring processing unit. According to the receiver, a multi-system signal monitoring technology, a broadband and narrowband combined monitoring technology and a multi-channel monitoring technology are adopted to realize the broadband and narrowband flexible configuration receiver. The device has the characteristics of simple equipment, reliable performance, low cost, good electromagnetic compatibility and the like.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a short-wave channel unit and a multi-channel monitoring receiver with wide and narrow bands that can be flexibly configured. Background technique [0002] In the field of spectrum monitoring, the current short-wave monitoring usually uses wide-band receivers or narrow-band receivers for radio monitoring and spectrum management of short-wave communication signals; wide-band receivers are used for radio monitoring of frequency-hopping signals. When simultaneous monitoring of broadband and narrowband is required, multiple devices are required to complete it together, the connection between devices is complicated, and the operation process is relatively cumbersome. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a flexible configurable shortwave channel unit and multi-channel monitoring receiver with wideband and n...
