摘要

摘要: 到达时间差(TDOA)直方图分析是电子支援侦察雷达信号主分选的基础；相关信号分选算法的性能与TDOA直方图脉冲重复间隔(PRI)检测门限的设定密切相关。为揭示PRI检测门限与TDOA直方图参数之间的关系，解决传统PRI检测门限依靠经验设定、无法灵活调整的问题，该文从分析TDOA直方图与脉冲序列的统计性质入手，推导了直方图稳定PRI、抖动PRI和参差PRI检测门限的解析表达式，提出了基于TDOA直方图PRI检测的信号分选算法，并通过仿真验证了算法的有效性。

Abstract: The Time Difference Of Arrival (TDOA) histogram is effective for pulse train de-interleaving in radar detection. The performance of TDOA-histogram based pulse sorting algorithm depends on several parameters in the histogram, such as the Pulse Repetition Interval (PRI) detection threshold and the box length, which are set posteriorly in traditional TDOA-histogram based algorithm. In this paper, the explicit expressions of detection threshold for various PRI modes (i.e. stable, jitter, and stagger) are derived, and the relationship among these parameters are revealed. Consequently, a signal sorting algorithm is proposed, and its performance is validated by simulation in complex signal environment.
