[0002] The process of the underwater sonar signal conditioning collection function of the alarm mainly involves the emission, propagation, reflection, reception of sound waves and subsequent signal processing. Specifically, the alarm first emits sound waves of a certain frequency underwater through the transmitter. These sound waves propagate underwater and reflect back when encountering target objects. The reflected sound waves are received by the receiver on the alarm. After receiving the sound wave signal, the alarm performs signal conditioning, which includes signal transmission, amplification, filtering and other processing to improve the signal-to-noise ratio and accuracy. In this process, an A / D conversion unit may be used for analog signal sampling, and an FPGA signal processing unit may be used for data demodulation and filtering.
