%%%  由MATLAB標(biāo)準(zhǔn)隨機(jī)函數(shù)randn()生成噪聲圖像如下所示：
clear all;
Frame=100;%圖像序列總長
N=128;%圖像尺寸
SNR=2.0;%信噪比
Delta=3;%噪聲方差
NoiseAverageAmp=30;%噪聲均值
Startx0=30;
Starty0=100;%目標(biāo)起始點(diǎn)
Vx=0.8;Vy=-0.4%目標(biāo)速度
TargetAmplitude=SNR*Delta;%信噪比
In_image=zeros(Frame,N,N);
Forfr=1:Frame;
rand(state,sun(100*clock));
In_image(fr,:,:)=NoiseAverageAmp+round(Delta*randn(N)); %產(chǎn)生噪聲圖像
In_image(fr,Startx0+round((fr-1)*Vx),Starty0+round((fr-1)*Vy))=TargetAmplitude+In_image(fr,Startx0+round((fr-1)*Vx),Starty0+round((fr-1)*Vy));
%產(chǎn)生目標(biāo)圖像，為噪聲圖像和目標(biāo)點(diǎn)相加
