Airborne Short-range Wireless Communication System Design And Implementation

With the rapid development of short-range wireless communication, the technology is used more and more widely in military and industrial fields. When not working in the guided missile range, in order to resolve the problem of synchronization with the system to access test flight parameters in time and guide the missile's flight track accurately, the flight test measurement system is put forward. The system is a dedicated measuring equipment of flight test parameters for missile target interception. It can present the real-time data of speed, height, position, track and relative motion parameters of the missile and target. A short-range wireless communication system, as a part of the flight test measurement system, is designed in this paper. Using the bomb rack interface, without modifying the circuit system and pneumatic architecture, the parameters of the missile have been sampled and transmitted to the other aerofoil by the system. 8-channel analog signal and ARINC-429 data acquisition is completed by hardware controlled by the hardware control logic circuit. The data is transmitted through single-chip wireless transceiver chip CC1100. Data modulation, demodulation, as well as up-conversion and down-conversion are completed in the chip cc1100. This method reduces the system costs, while shortening the development cycle. The system uses MSK modulation. The advantages of the modulation are high bandwidth efficiency and Small-band radiation. In this way the performance of the system greatly improved. In addition, The system uses a FPGA to do the master chip. The use of hardware logic for system control, greatly improved the system reliability and stability. In this way the system can ensure that poor environmental conditions in the air in the normal work. The system has been through a variety of environmental testing, and has been applied in the flight test system parameters. At the same time, Because of the programmable FPGA and programmable features of the CC1100, the hardware structure of the system has good portability. The system can be applied to a wide range of remote telemetry systems, have good practical value.
