摘要

针对黑匣子等弹载记录设备搜寻困难的问题

设计了一种基于BPSK（二进制相移键控）调制方式的无线信标机。选用U-BLOX公司的GPS（全球定位系统）模块NEO-5Q自我定位

使用DDS（直接数字频率合成器）芯片AD9910进行高频BPSK调制

再将信标数据帧通过射频电路板以一定频段发射。经实测

该设计可以得到输出功率达1.9mW、频段为400MHz以上的BPSK调制信号。该设计是借用软件无线电的思想

通过软件实现无线电台的各种功能

具有灵活性与开放性的特点。

Abstract

In view of the difficulties of black box or other missile-borne recording equipment in searches

this paper proposes a BPSK modulation-based design for radio beacon machines.This design selects u-blox GPS NEO-5Q module for self positioning and DDS chip AD9910 for HF BPSK modulation and then emits the beacon data frame at a certain frequency band via an RF circuit board.Actual measurement shows that this design can obtain BPSK modulated signals with the output power of up to 1.9 mW at over 400 MHz.Using the idea of software radio

this design implement various function of radio stations by software and has features of flexibility and openness.
