对于具有动目标检测信号处理功能的空中交通管制雷达,本文推导了扩大不模糊速度间隔可容许的脉冲重复频率参差比,并根据模拟,介绍了表示速度信息可靠性的各种参数公式和曲线。在只有噪声的环境中和对于其信噪此导致P_d=90％的斯惠林1目标来说,获得速度信息的概率大于50％,扩大的不模糊速度间隔为832节,标准偏差小于1节。虚警测量概率小于10~(-5)。
For air traffic control radar with moving target detection signal processing capability, this paper deduces the allowable pulse repetition frequency variation ratio of unambiguous velocity interval. Based on the simulation, the formulas and curves of various parameters representing the reliability of velocity information are introduced. In a noise-only environment and for a Sputtway 1 target whose signal-to-noise is P_d = 90%, the probability of obtaining velocity information is greater than 50%, the expanded unambiguous velocity interval is 832 knots and the standard deviation is less than 1 knot . False alarm measurement probability is less than 10 ~ (-5).
