| 摘 要： | 由于水声环境复杂,为了检测环境噪声干扰下的测距回波信号,需要较强的发射信号,造成系统功耗高,无法长时间工作,保密性差。将混沌检测理论引入水声测距领域,发现混沌振子检测方法适用于超声测距,符合该方法固有的限定条件。同时,在理论上对混沌检测方法进行了改进,并给出了具体的硬件结构。

| Abstract: | The Duffing oscillator is applied to solve high transmitter power consumption, and the weak signals can be used as the outside periodic exciter and be brought in the Duffing oscillator system.The Duffing oscillator detection in ultrasonic distance measurement is improved.The measurement is brought forward as a cirterion to state of chaos.Duffing oscillator cannot detect target because of phase deviation.The detector is designed to measure distance.Simulation model, frame diagram and simulation result are gi... |
