Example Embodiment

[0020] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] like figure 2 with image 3 As shown, an array-type radio trunk of the present invention includes an array patch receiving antenna 1, a patch emission antenna 2, a multi-channel transceiver circuit 3, and a signal processing circuit 4.

[0022] The plurality of separate patch antennas in the antenna 1 constitute an array to form a multi-channel array receiving antenna, and each receiving channel in the receiving circuit corresponds to a group element in the antenna in the antenna.

[0023] The transmitting antenna 2 also uses a patch antenna, an antenna may be in a single or array, the antenna polarization direction is the same as the receiving antenna, and the beam width can be customized as needed.

[0024] like Figure 4 As shown, the signal processing circuit built into a digital beamforming algorithm. Digital beamforming is directed to the array antenna, using the aperture of the array antenna, forming a received be

Abstract

The invention discloses a radio fuse of an array patch antenna. The radio fuse comprises the array patch antenna, a multi-channel frequency modulation continuous wave transceiving circuit and a signal processing circuit. The array antenna can achieve beam forming, target detection is more flexible than a single antenna mode, the multi-antenna structure supports phase-comparison angle measurement, and angle information except distance and speed can be obtained. According to the array patch type radio fuse provided by the invention, a better fuze detection effect can be realized in a volume allowable range.
