Abstract

The invention discloses a multichannel small broadband receiver, which comprises a signal processor, a small broadband antenna group and a broadband radio frequency receiving front end group, whereinthe broadband radio frequency receiving front end group is positioned between the small broadband antenna group and the signal processor; the small broadband antennas in the small broadband antenna group are connected with the broadband radio frequency receiving front ends in the broadband radio frequency receiving front end group in a one-to-one correspondence manner; the small broadband antennagroup is used for receiving broadband microwave signals in a space; the broadband radio frequency receiving front end group amplifies, filters and down-mixes the broadband microwave signal into an intermediate frequency signal and sends the intermediate frequency signal to the signal processor; and the signal processor is used for carrying out analog-to-digital conversion on the intermediate frequency signal, converting the intermediate frequency signal into a digital signal and then carrying out digital signal processing. Under the condition that the function is not changed, the size of a conventional system can be greatly reduced.

Description

technical field [0001] The invention relates to the field of microwave receivers, in particular to a multi-channel small broadband receiver. Background technique [0002] With the rapid development of wireless technologies such as mobile communication, satellite communication, and radar, communication and radar frequencies are developing towards high frequency bands and broadband. In order to better detect and receive communication and radar signals, microwave receivers will develop in the direction of broadband, miniaturization and portability. [0003] Searched domestic and foreign databases for the existing technology. Patent CN201711437680.3 "A Low-Frequency Broadband Receiver System", published on June 15, 2018, provides a low-frequency wideband receiver system, including front-end circuit systems, The analog-to-digital conversion circuit system and the digital operation board of the telescope; the front-end circuit system includes a primary processing module, a second...
