单矢量传感器信号处理方位估计

Estimating the azimuth of signal processing using single vector-sensor

研究基于压差式矢量传感器声压振速联合处理的方位估计算法,获取目标真实方位。采用频数直方图对信号的每个采样区间内的一定采样点数的瞬时方位估计值进行统计,统计出该采样区间内的方位值集中数目,方位值集中数目最多的方向则表明该方向声能流最大,即为目标方向。水池试验结果验证了频数直方图方法可以有效剔除目标估计中界面反射干扰信号引起的方位估值,获得目标真实方位。

The pressure and particle velocity combined processing technology based on an acoustic vector-sensor is applied to the direction estimation for target. Histogram azimuth angle estimation, is applied for statistical instantaneous angle estimation in every bin, counting the same azimuth angle number, the maximum number show the azimuth angle that is main energy signal of target. Test result show the histogram is good for azimuth angle estimation in pool. The approach can eliminate disturbing signal and the reflex interface signal target of angle estimation.
