Abstract

Произведена оценка влияния флуктуационных стационарных мультипликативных помех, действующих одновременного с аддитивными помехами, на точность измерения неэнергетических параметров информационных сигналов. Показано, что мультипликативная помеха низкого уровня оказывает более сильное влияние на точность измерения времени прихода, чем на точность измерения частоты полезного сигнала. Осуществлена количественная оценка влияния мультипликативной помехи на точность измерения неэнергетических параметров полезного сигнала. The influence of fluctuating stationary multiplicative interference acting simultaneously with additive interference on the accuracy of measurement of non-energy parameters of information signals is estimated. It is shown that low-level multiplicative interference has a stronger effect on the accuracy of the arrival time measurement than on the accuracy of the useful signal frequency measurement. A quantitative assessment of the effect of multiplicative interference on the accuracy of measurement of non-energy parameters of the useful signal is carried out.

低水平加性和乘性干扰下航空和航天火箭无线电系统信号信息参数测量的精度。第2部分(频率和到达时间测量有用信号的例子)
我们评估了与相加干扰同时作用的波动静态相乘干扰对信息信号非能级参数测量精度的影响。结果表明,低电平乘法干扰对到达时间测量精度的影响比对有用信号频率测量精度的影响更大。对乘法干扰对有用信号非能动参数测量精度的影响进行了定量评估。估算了与相加干扰同时作用的波动静态相乘干扰对信息信号非能量参数测量精度的影响。结果表明,低电平乘法干扰对到达时间测量精度的影响比对有用信号频率测量精度的影响更大。对乘法干扰对有用信号非能量参数测量精度的影响进行了定量评估。
