本文叙述了相握线列阵（等加权和非等加权）用于水下超声成像观察阵时的波束特性。根据随机误差理论。本文给出了在阵元相位、振幅随机起伏时，相控线列阵的尖峰旁瓣的估计。 此外，本文对声图像点进行了模拟观察。并将某些计算机模拟到的随机旁瓣特性与通过随机误差理论估算获得的结果进行了比较，两者基本一致。本文还详细地研究了影响尖峰旁瓣特性的诸因素。并根据随机相位、振幅误差和阵元失灵，提出了相拴线列阵的设计指标。 本文可供设计其他超声成像阵列时参考。
This paper describes the phase-locked linear array (equal and non-weighted) for underwater ultrasound imaging observation beam array characteristics. According to random error theory. In this paper, we give the estimation of the spike sidelobes of the phased array when the phase angle and amplitude of the array element fluctuate randomly. In addition, this paper simulates the acoustic image points. The random sidelobe characteristics simulated by some computers are compared with those obtained by stochastic error theory. The two are basically the same. This article also studies in detail the various factors that affect the spike sidelobe characteristics. According to the random phase, amplitude error and array element failure, the design indexes of phase tethered array are proposed. This article is available for reference when designing other ultrasound imaging arrays.
