Abstract

The invention discloses a high frequency and vary-high frequency broad band signal processing system and method. The system comprises a harmonic filter, a first mixer connected with the harmonic filter, a low-pass filter connected with the mixer, a first path switch respectively connected with the harmonic filter and the low-pass filter, an automatic gain control device connected with the first path switch, an analog-to-digital converter connected with the automatic gain control device, an on-site programmable gate array device connected with the analog-to-digital converter, a second mixer connected with the on-site programmable gate array device, a band-pass filter connected with the second mixer, a second path switch respectively connected with the band-pass filter and the on-site programmable gate array device, a digital to analog converter respectively connected with the second path switch and the harmonic filter, and an information channel detector. The system has the benefits of being more miniaturized and integrated and reducing power consumption.

Description

technical field [0001] The invention belongs to the technical field of high-frequency and very high-frequency signal processing, and in particular relates to a high-frequency and very high-frequency broadband signal processing system and processing method. Background technique [0002] Nowadays, the signal processing of high frequency (HF: 1.6MHz ~ 30MHz) and very high frequency (VHF: 30MHz ~ 60MHz) is completed by different hardware platforms respectively, which makes the hardware platform of the whole signal processing bulky and not easy to carry , failed to achieve integration and miniaturization. [0003] In addition, in the existing high-frequency or very high-frequency signal processing hardware platform, the high-frequency channel and some very high-frequency channels are usually detected in real time, and the high-frequency channel or the very high-frequency channel is determined according to actual needs, and then selected Can work in frequency band (HF or VHF) and...
