在反隐身、浅层地下目标勘探、反射地震勘探等领域越来越多地运用宽带或超宽带信号的雷达体制．由于信号传播色散的影响，经典的相关估计方法不能有效地估计目标信号的时延等参数．针对这种情况，该文给出了宽带相关信号参数的估计模型，在已知源信号情况下提出了估计的方法，并对估计器的性能进行了详细的理论分析．最后，应用这种方法分析了模拟和实测的雷达数据，结果表明，这种方法可以精确、有效地估计时延等参数．
In the anti-stealth, shallow subsurface exploration, reflective seismic exploration and other fields more and more use of broadband or ultra-wideband signal radar system. Due to the influence of signal dispersion, the classical correlation estimation method can not effectively estimate the parameters such as the delay of the target signal. In view of this situation, the paper gives the estimation model of broadband related signal parameters, proposes the estimation method when the source signal is known, and analyzes the performance of the estimator in detail. Finally, this method is used to analyze the simulated and measured radar data. The results show that this method can accurately and effectively estimate the delay and other parameters.
