一种实现模拟海浪回波产生的电路

A Realization of a Circuit by Simulating Ocean Wave Echo

无风三尺浪是大海的特点,当海上有浪时,从海面上远望,海浪由近及远是逐步减弱的,一般情况下,越近的距离海浪越大,在这种海况下,雷达天线发射的无线电波遇到海浪便会反射回来,反射回来的无线电波的功率随海浪由近及远是逐步减弱的,我们可以用一个具有模拟指数衰减曲线功能的电路模拟该功能,在电路中模拟产生了强、中、弱三种状态海浪的信号,通过模拟器面板上的波段开关可以控制海浪信号的强、中、弱三种状态,在电路中通过采用压控振荡器及速率乘法器等器件实现了以上功能。

The calm three foot waves are the sea characteristics, when marine has the wave, far looks from the sea level, the ocean waves by near and far are weaken gradually, in the ordinary circumstances, we may observe to a nearer distance, the ocean waves bigger, under this kind of sea condition, the radio wave which the radar antenna launches meets the ocean waves then to be able to reflect, reflects the radio wave power by near and far is weaken gradually along with the ocean waves, we may use to have the simulation exponential decay curve function the electric circuit to simulate this function, simulated in the electric circuit produces has been strong, center, the weak three kind of conditions ocean waves signal, May control the ocean waves signal through the simulator kneading board on range selector, center, the weak three kind of conditions, through used the pressure in the electric circuit to control component and so on oscillator and speed multiplier has realized above the function.
