摘要:
针对随机噪声信号的分辨能力,推导出了不同功率谱形式的噪声信号的雷达目标距离分辨率表达式。理论分析基于信号的时间相关函数,利用Taylor级数和高次方程求解方法。理论结果表明:在相同的信号带宽情况下,具有高斯功率谱形式的噪声信号比矩形功率谱噪声信号具有更好的距离分辨率,也比常规线性调频信号有更高的距离分辨率,但高斯功率谱形式的噪声信号和线性调频信号可以具有相同的能量。仿真结果验证了理论分析的正确性。
Abstract:
Aiming at the resolution ability of random noise signal,a mathematic expression of range resolution is derived for random noise signal on the rectanglular and the Gaussian shaped power spectra.Based on the time correlation function of signal,Taylor series and high-order equation solving method is employed in theoretical derivation.The result shows that the random noise signal on the Gaussian shaped power spectra possesses better resolution ability in comparison with the random noise signal on the rectanglular shaped power spectra and the linear frequency modulation signal in the case of equal bandwidth,but their energy may be equal.Simulation illustrates the validity of the theoretical calculation.
