摘要
针对逐脉冲序贯重频参数估计的场景,引入了评估变量控制对脉冲的缓存,对受漏脉冲和干扰脉冲等数据噪声污染的脉冲列进行了较高精度的参数估计;进一步对缓存区间内的脉冲采用试探整除的方法,对脉冲多普勒雷达截获脉冲列中重频切换的跳变时刻进行了跟踪检测.仿真实验验证了文中所提的重频参数序贯估计方法相较于传统重频参数估计方法在序贯估计场景下的有效性和优越性.
Abstract
The evaluation variable control of the pulses was introduced to the scenario of sequential PRI estimation in this paper,enabling a higher-precision parameter estimation of pulse sequences contaminated with data noise such as missing and interference pulses.Furthermore,a probing integer division method was applied to the pulses within the buffer interval to track and detect the discontinuity moments of PRI switching in the pulse Doppler radar intercepted pulse sequence.Simulation experiments verified the effectiveness and superiority of the proposed sequential PRI estimation method compared to traditional PRI parameter estimation methods in sequential estimation scenarios.
