Abstract

The simultaneous influence of multiplicative and additive noises on the steepness of the discriminative characteristic of a two-channel discriminator is analyzed. A coherent signal and a sequence of incoherent pulses are used as input signals. It is assumed that, at a relatively low level of noise, the tracking meter is considered as a linear system. Conditions are obtained when systematic measurement errors are absent. The expressions for determining the steepness of the discriminative characteristic affected by multiplicative noise depending on the additive noise level are obtained. It is shown that multiplicative noise has a greater influence on the steepness of the discriminative characteristic when the level of additive noise is higher. Coefficients determining the normalizing effect of the automatic gain control are obtained. It is shown that the type of the input signal does not change the physical nature of the influence of multiplicative and additive noises on the steepness of the discriminative characteristic.

信号非能量参数计的判别特征陡度的确定

分析了乘性噪声和加性噪声对双通道鉴别器判别特性陡度的同时影响。使用相干信号和非相干脉冲序列作为输入信号。假设在相对较低的噪声水平下，跟踪仪被认为是一个线性系统。得到了系统测量误差不存在的条件。得到了判别特性受乘性噪声影响的陡度随加性噪声电平的表达式。结果表明，当加性噪声水平越高时，乘性噪声对判别特征的陡度影响越大。得到了决定自动增益控制归一化效果的系数。结果表明，输入信号的类型不改变乘性噪声和加性噪声对判别特征陡度影响的物理性质。
