The vehicle-mounted device comprises an antenna, a radio frequency signal amplifier, a receiver, and a transmission channel, wherein the radio frequency signal amplifier is connected with the antenna; the transmission channel is connected between the receiver and the radio frequency signal amplifier; the antenna is used for receiving radio frequency signals; the radio frequency signal amplifier is used for receiving the radio frequency signals from the antenna and amplifying the radio frequency signals, and radio frequency signals after amplification are acquired; and the receiver acquires the radio frequency signals after amplification from the radio frequency signal amplifier through the transmission channel. Through the technical scheme provided by the invention, the technical problem that enhancement of the system sensitivity of the vehicle-mounted device in the prior art is limited can be solved.

Description

technical field [0001] The invention relates to the technical field of signal detection, in particular to a vehicle-mounted device and a radio frequency signal amplification method. Background technique [0002] In the field of electronic countermeasure detection, detection distance is a very important performance parameter of detection equipment. A longer detection distance can detect targets earlier to win the corresponding initiative. [0003] In practical applications, for detection equipment that receives signals from specific radiation sources, the detection distance can only be extended by increasing the system sensitivity of the detection equipment. At present, the general methods to improve the sensitivity of the detection equipment system are: to compress the antenna beam width as much as possible to increase the antenna gain; or to use high-performance low-loss cables and low-loss rotary joints to reduce the cable length; or to optimize the receiver scheme and sig...
