请帮我看一个程序，看这个是什么意思，关于卡尔曼滤波的
% modeling data% sample number N=200 points
% sample time T=0.1s
t=0:0.1:20-0.1;
T=0.1;
% sample time
v=0.5;
% initial velocity
y=ones(1,200);
y(1)=0;
for n=2:200;
y(n)=y(n-1)+v*T;
end
figure(1);
plot(t,y,'-');
axis();
xlabel('time');
ylabel('yp position');
title('the initial track of movement');
% add white gauss noise
a=0.5*randn(1,200);
s=y+a;
%data+noise
figure(2);
plot(t,s,'+');
axis();
xlabel('time');
ylabel('yp position');
title('the track of movement with noise');
save initial_track
s
谢谢
