Embodiment Construction

[0014] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0015] The structure of the equipment is designed as figure 1 As shown, the support ring, heat sink, sealing cover, air outlet, and mounting seat form a physical structure as support components to provide support, sealing, heat dissipation, and interfaces for the equipment; the support ring includes upper and lower support rings, and the heat sink includes several A central heat sink and several edge heat sinks are made of thermally conductive materials. The central heat sink is connected to the upper and lower support rings through corner pieces and fasteners, and the edge heat sinks surround the upper and lower support rings to form a circular platform structure. The control module, noise The bottom of the module, power distribution module, and antenna module is coated with thermally conductive silicone grease, distributed and installed...

Abstract

The invention discloses anti-drone interference equipment based on a phased circular array. The anti-drone interference equipment comprises a support assembly, a power supply module, a control module,a noise module, a power division module and an antenna module which form a circular truncated cone shaped sealed cover shell structure, wherein an ARM unit and an FPGA unit analyze an interference instruction, set working parameters and generate broadband and narrowband noise signals of an L waveband, an S waveband and a C waveband, and 360-degree omnibearing electric scanning and interference ofdrone targets at various distances are achieved through utilizing a circular array formed by amplifying, phase shifting and antenna switching units.

Description

technical field [0001] The invention belongs to the field of radar microwave technology, and in particular relates to an unmanned aerial vehicle interference technology. Background technique [0002] With the development and application of unmanned aerial vehicle (UAV) technology, various small unmanned aerial vehicle (UAV) black flights, illegal intrusions and terrorist attacks pose serious challenges to the existing air defense systems and public area security of various countries. UAVs have the characteristics of "low, small, and slow" and are not easy to be found, posing a great threat to the defended target. Therefore, it is of great significance to build a defense system for UAVs. All countries are vigorously developing anti-drone technology, and so far, there are various anti-drone systems. However, the anti-drone jamming devices currently on the market are basically handheld or servo machines, with a single frequency band, inflexible tracking, and inability to track...
