对于具有 MTD 型信号处理的空中交通管制雷达(ATC Radar),导出了在扩展速度下模糊区间的情况下允许的脉冲重复频率参差比,并且在模拟的基础上提出了描述速度信息可靠性参数的公式和曲线。在只有噪声的情况下,对具有能产生 Pd=0.9的信噪比的斯威林Ⅰ型目标(Swerling 1),在扩展的速度不模糊区间内为832节和标准偏差小于1节的条件下,获得速度信息的概率大于50%,虚(?)测量的概率小于10~(-5).
For the ATC Radar with MTD signal processing, the pulse repetition frequency variation ratio allowed in the case of the fuzzy interval at the extended speed is derived. Based on the simulation, the parameter describing the reliability of the velocity information Formulas and curves. Under the condition of noise only, for Swerling 1 with signal-to-noise ratio of Pd = 0.9, under the condition of 832 knots in the unambiguous speed range and less than 1 standard deviation , The probability of obtaining speed information is more than 50% and the probability of virtual (?) Measurement is less than 10 ~ (-5).
