摘要

摘要: 该文提出了一种基于魏格纳分布(Wigner-Ville Distributed, WVD)和重构时间采样(Reconstruction timesample, RTS)的空中机动目标检测和参数估计方法。该方法首先利用雷达回波的空域采样来重构时域采样,相当于增加了单个阵元的脉冲采样点数,然后再对重构后的数据进行WVD变换来估计目标的参数。该方法能够在方位信息未知,脉冲数较少的情况下有效地实现对机动目标的检测与参数估计。仿真结果验证了该方法的有效性。

Abstract: A novel detection and parameter estimation method for air maneuvering target based on reconstruction time sample and Wigner-Ville Distributed (WVD) is proposed in this paper. Firstly, reconstruct time sampling method is applied to reconstruct the signal by using the space samples, which is equivalent to increasing the number of time samples within a Coherent Processing Interval (CPI). Then WVD method is utilized for reconstructing signals to achieve parameter estimation. The proposed method can achieve the detection and parameter estimation of the maneuvering target effectively without the need of precisely known of azimuth of target when the data sample is limited. The simulation result is provided to demonstrate the effectiveness of the proposed method.
