    摘  要:针对现有弹载记录仪回收方法存在的效率低、功耗大等不足,设计应用于弹载记录仪回收的新型低功耗无线电搜寻定位系统。该无线电搜寻定位系统搭载于无人机,主要由无线通信模块、GPS定位模块、Flash存储模块、中央控制模块等构成。载有信标装置的弹载记录仪着地后,无线通信模块接收信标发射的无线电波,GPS定位模块定位无人机对应坐标,中央控制模块将无线电信号强度值和对应GPS坐标存储于Flash芯片,无人机工作一定时间后返回,上位机读取存储信息,利用RSSI定位算法和三边测量方法估算信标位置,从而快速回收弹载记录仪。通过定点模拟试验验证该定位系统的可实现性,为以后的弹载记录仪回收提供有效的方法。

    Abstract: A new type of low-power radio searching and positioning system is designed for recovering missile-borne recorders. The system mounted on an unmanned aerial vehicle (UAV) is composed of a wireless communication module, a GPS positioning module, a FLASH memory module and a central control module. After the recorder with a beacon device is landed, the wireless communication module received the radio wave emitted by the beacon and the GPS positioning module located the UAV coordinates. Then, the central control module stored the radio signal strengths and their GPS coordinates in the Flash chip. After running a certain period of time, the UAV returned, and meantime the host computer begins to read the stored data. Next, the beacon position is estimated with RSSI positioning algorithm and three-edge measuring method so that the missile-borne recorder can quickly recovered. The fixed-point simulation test has verified the realization of the system and has provided a new approach for reusing missile borne recorders.
