A method for eliminating sudden changes in transmitter power supply voltage or current when transmitting high-power signals

Abstract

The invention discloses a method for solving voltage or current mutation of a transmitter power supply during high power signal transmission and belongs to the technical field of sonar detection. A plurality of discrete points are inserted into the connection position of two sections of signals with discrete phases to enable the phases of the head signal and the tail signal of the two sections of signals to be connected. The method includes the following steps: calculating the number N of the inserted discrete points, calculating the sum theta0 of the phases of the inserted discrete points, calculating the stepping phase theta of the discrete points and conducting signal transmission. The method has the advantage that the method finishes real-time calculation for smooth connection of the head phase and the tail phase of pulse signals in different transmitting directions, enables the discrete signal phases to be connected smoothly, ensures transmission efficiency of the transmitter, and ensures hardware safety of the transmitter. The method is simple in calculation and good in adaptability. High power transmitting tests prove that the method can effectively remove voltage or current mutation of the transmitter power supply and has high practical value.

Description

technical field [0001] The invention aims at a solution for eliminating the sudden change of the power supply voltage or current of a transmitter when a high-power signal is transmitted, and is mainly used for high-power transmission of a sonar device to protect the safety of the transmitter hardware, and belongs to the technical field of sonar detection. Background technique [0002] In the target detection mode of sonar equipment, the active working mode is one of the most important working modes. When the sonar detection equipment transmits different azimuth signals in the active working mode, the initial phase of each transmission channel signal is related to the spatial azimuth of the transmission, so the transmission of different azimuth signals has different initial phases of transmission, so that each of the two transmission beams before and after The signal phase of the transmitting channel will have a sudden change. In the process of active signal transmission, th...

AI Technical Summary

Problems solved by technology

In the process of active signal transmission, the discontinuity of the signal phase will reduce the transmission efficiency of the transmitter, resulting in sudden changes in the power supply voltage or current of the transmitter, and even damage to the hardware of the transmitter

At present, when the signal source of sonar equipment transmits signals of different azimuths within a transmission period, it generally adopts the method of inserting an interval between two transmitted pulse signals, and the disadvantage of this method is that it will increase the blind area of ​​sonar equipment detection
