摘要

本研究的目的是确定使用商用现成的基于FPGA的软件定义无线电系统来分析和理解小型无人机通信协议的可能性,以便劫持或智能干扰接收器。对DSM2通信协议的解码进行了研究。为了理解协议,使用软件定义无线电和LabView软件收集原始射频数据。在MAT LAB中编写了一套分析数据、提取突发、同步和解调芯片的工具。在创建反无人机系统时,理解通信是至关重要的。最后分析了DSM2通信协议被智能干扰的可能性。

Software Defined Radio for Analyzing Drone Communication Protocols
The aim of this research is to determine the possibilities of using commercial off the shelf FPGA based Software Defined Radio Systems to analyze and understand small drone communication protocols in order to hijack or smart jam the receiver. A study on decoding the DSM2 protocol of communication is presented. In order to understand the protocol, raw RF data were collected using Software Defined Radio and LabView software. A set of tools were written in MAT LAB to analyze the data, extract the bursts, perform synchronization and demodulate the chips. Understanding the communication is vital when creating a counter drone system. The possibility of smart jamming the DSM2 protocol of communication is analyzed in the final part of the paper.
