采用多基地探测方式，具有探测距离远、隐蔽性好的特点，成为当前研究的热点。而相较传统的主被动探测方式，该方法在信号接收方面存在一定的差异。由于探测目标改变较大，过程中需要考虑混响对接收信号的影响，同时为不影响探测的准确性，需选择合适的检测器，以保持恒定的虚警率，最终完成目标接收的全过程。本文通过对水下环境、目标特性及接收端恒虚警技术的研究，采用适当算法对过程中的影响因素进行分析，确保多基地探测目标的可靠性。
The multi-base detection method has the characteristics of long detection distance and good concealment, which becomes the hot spot of the current research. Compared with the traditional main and passive detection methods, this method has some differences in signal reception. With the detection target characteristics changing greatly, the influence of reverberation on the received signal should be considered in the process. In order not to affect the accuracy of the detection, an appropriate detector is selected to maintain the constant false alarm rate and finally complete the whole process of target reception. This paper mainly studies the underwater environment, target characteristics and the receiver. Ensure the reliability of multi-base detection targets.
