摘　　要：利用GSL开源科学计算库的强大计算功能,实现了主动定向浮标信号处理的编码。采用互谱法求CW回波信号目标方位,依据目标多普勒频移来测速。并做了距离方位可视化显示,使得目标方位显示直观明了。Using the strong computing ability of GSL,coding Directional Sonobuoy signal process is realized.In our algorithm,target bearing of CW signal is calculated by cross spectrum method and target speed is calculated by Doppler frequency shift.In order to make target display intuitire and clear,range to bearing display visualization is done in this paper.
