[0031] In order to make it easy to understand the technical means, creative features, objectives and effects achieved by the present invention, the present invention will be further explained below in conjunction with specific drawings.
[0032] The basic principles of mobile channel detection and perception are as follows figure 1 As shown, the figure is a schematic diagram of a V2V communication scenario. Through the distributed array antenna detection method, the spatial channel characteristics can be directly obtained, which effectively improves the spatial resolution of the mobile channel, and provides a guarantee for subsequent real-time channel multi-dimensional analysis. The spatial combination of beam scanning antennas is used to realize a loop antenna array. The switching of the antenna radiation pattern adopts a DC feed control method, and the switching between antennas is realized by a high-speed microwave switch. The method can directly obtain the transmit and receive...
