摘要
分析适用于模糊区与近似清晰区的白噪声模糊函数中心主峰附近的指数衰减模型,推导了模型参数的数值计算公式。在模糊函数表达式的基础上,导出了高斯白噪声的多普勒补偿公式。仿真结果验证了指数衰减模型的正确性,验证了高斯白噪声的多普勒补偿方法的有效性。
An exponential attenuation model of main peak about white noise' s ambiguity function is analyzed, and the numerical formula of the model is deduced. According to the ambiguity function, Doppler compensation formula about white noise is also deduced. The simulation results illuminate the effectiveness of the exponential attenuation model and the Doppler compensation method.
