一个全数字化工作的脉冲序列跟踪器能在密集的信号环境中跟踪多个脉冲序列。截获电路测量在预定的最小和最大周期范围内的连续脉冲之间的脉冲周期而确定单一脉冲组的存在。被截获的脉冲序列由多个跟踪电路中的一个进行跟踪,这样就能独立地跟踪重复频率相同或不同的多个脉冲序列。跟踪器对于被跟踪的序列预测其脉冲周期以及形成选择后续脉冲的波门。跟踪器在每个周期内相对于收到的脉冲校正波门的相位以及按比例校正脉冲周期。跟踪器在预定的数个脉冲周期内丢失脉冲仍能保持跟踪。
A fully digitized pulse train tracker tracks multiple pulse trains in a dense signal environment. The intercept circuit determines the presence of a single pulse set by measuring the pulse period between consecutive pulses within the predetermined minimum and maximum period range. The intercepted pulse sequence is tracked by one of a plurality of tracking circuits so that multiple pulse sequences of the same or different repetition frequency can be tracked independently. The tracker predicts the pulse period of the tracked sequence and forms the gate that selects the subsequent pulse. The tracker corrects the phase of the wave gate relative to the received pulse and the scaling of the pulse period within each cycle. The tracker can keep track of missing pulses for a predetermined number of pulse periods.
