Embodiment Construction

[0025] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .

[0026] like Figure 1-4 As shown, the present invention provides a long-range radar detection system, including the long-range radar detection system including an antenna feeder assembly, a channel module, a signal processing module, and a display and control module.

[0027] Wherein, one end of the channel module is connected to the antenna feeder component, and the other end is connected to the signal processing module. The channel module is used to generate the first intermediate frequency signal and up-convert the first intermediate frequency signal into a radio frequency signal and radiate it through the antenna feeder component, and is used to r...

Abstract

The invention discloses a remote radar detection system. The remote radar detection system comprises an antenna feeder assembly, a channel module, a signal processing module and a display and control module, the channel module is used for generating a first intermediate-frequency signal, up-converting the first intermediate-frequency signal into a radio-frequency signal, radiating the radio-frequency signal through the antenna feeder assembly, receiving an echo signal returned by the antenna feeder assembly, down-converting the echo signal to generate a second intermediate-frequency signal, and sending the second intermediate-frequency signal to the signal processing module; the signal processing module is used for carrying out pulse compression processing on the received second intermediate frequency signal and then detecting a target object according to a moving target detection algorithm; and the display and control module is used for displaying the related data sent by the signal processing module and sending an external control instruction to the signal processing module, so that the signal processing module controls the working states of the antenna feeder assembly and the channel module according to the external control instruction. The system can be used for detecting targets with low, slow and small characteristics, and the radar detection precision is greatly improved.

Description

technical field [0001] The invention relates to radar detection, in particular to a long-range radar detection system. Background technique [0002] At present, the existing radars are generally only for long-distance early warning detection, and their detection distance is long, the detection range is wide, and the wave band adopts L / S band, and the wave band is about 30cm. With the development of science and technology, drones are becoming more and more common. Existing radars cannot detect targets with a body below 30cm, making it impossible to detect smaller targets such as drones and birds. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a long-range radar detection system, which can solve the problem that radar detectors in the prior art cannot detect targets such as drones and birds. [0004] The purpose of the present invention adopts following technical scheme to realize:...
