发射信号与回波信号混频后得到的差频信号频率为
式中:fＴ(t)表示发射信号的频率;fＲ(t)表示接收信号的频率.可见,差频信号的频率与液面距离成正比.由于液面对电磁波的反射可近似为镜面反射,差频信号在理想状态下是单频信号,为提高测距精度,需采用信号处理算法对差频信号的频率进行测量.
2、差频信号处理算法分析：
2.1、栅栏效应对测距精度的影响：
雷达液位计采用数字信号处理方式,对差频信号进行采样后进行FFT处理,得到差频信号的频谱,***简单的测量方法是通过直接寻找谱峰测得差频信号的频率.实际应用中,FFT的栅栏效应会影响频率检测的准确度.假设对差频采样信号做Nｆ点的FFT,栅栏效应产生的频谱谱线间隔为δf=Fｓ/Nｆ,其中Fｓ为采样频率.若Nｆ与差频信号的采样点数N相同,则δf=Fｓ/N=1/T,将其代入式(1)~式(3)可得栅栏效应导致的距离测量离散化,相应的距离离散单元可表示为
