Problems solved by technology

The single-antenna fuze has only one receiving channel, which can calculate the speed and distance information, but cannot obtain the angle information of the target. The single antenna cannot be beam-synthesized, and the direction switching of the beam cannot be realized in the digital domain. The anti-interference performance does not support multi-antenna beam switching. Fuze effect is good

Embodiment Construction

[0020] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

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

[0022] Multiple independent patch antennas in the receiving antenna 1 form an array to form a multi-channel array receiving antenna, and each receiving channel in the receiving circuit corresponds to an array element in the array receiving antenna.

[0023] The transmitting antenna 2 also adopts a patch antenna. The antenna can be in the form of a single or an array. The polarization direction of the antenna is the same as that of the receiving antenna, and the beam width can be customized according to needs.

[0024] Such as Figure 4 As shown, the signal processing circuit has a built-i...

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.

Description

technical field [0001] The invention belongs to the field of radio fuzes, in particular to an array patch type radio fuze for multi-channel wireless reception. Background technique [0002] The fuze is a device that uses environmental information, target information, or according to pre-set conditions, under the premise of ensuring the safety of the ammunition at ordinary times and when it is fired, to implement detonation control, ignition control and attitude control on the ammunition. To a certain extent, the performance of the fuze directly determines the damage effectiveness of the weapon system. With the continuous development of radar technology, the fuze adopts radar technology to evolve into a radio fuze, which mainly uses the target echo signal to obtain target distance, relative speed, target angle and other information. FM radio fuze is a kind of constant-amplitude continuous wave radio fuze whose transmission signal frequency changes according to the law of mod...
