| 摘 要： | 被动声纳中,目标定位的测定只能利用目标声源发出的信号或噪声,爆炸声源与常用的电声式脉冲声纳发射器比较起来,具有某些明显的优点,可代替发射换能器来实现距离和方位的测定.针对水下爆炸声源,采用三元标量阵进行研究,通过确定信号到达各个阵元的时延信息来测定其目标方位和距离,并利用内插方法提高定位精度.实验结果表明,不同位置处爆...

| Abstract: | Noise or signal radiated from target is used to detect the target distance and azimuth in the passive sonar.The explosive sound source has some obvious advantages compared to pulse sonar transmitters,which can detect the target distance and azimuth instead of transmitter transducer.The three-scalar array is used to research on underwater explosion by obtaining the time delay information to achieve the estimation of distance and azimuth.The interpolation method is used to improve the precision of time delay ... |
