simulating radar targets vibrating at a low frequency
显示 更早的评论
Is it possible to simulate mechanically vibrating targets in order to perform micro-doppler signature processing? doesn't have to be complex motion (like jet engine blades) but something like a spherical target that periodically expands and contracts, say about 1% its mean volume?

me to having similar problem but in my case the rcs is not fluctating instead target is placed on a vibrating platform .how to define the position and veklocity of such platform

There is no existing solution for this in Phased Array System Toolbox, but if the purpose is to model a sphere, it can be done manually since the RCS of a sphere is simply given by pi*r^2 where r is the radius.
So in your code, you can consider a mean value of r and then define a period of the expansion/contraction. Then at each simulation step, you can compute the r based on the period and then use the resulting r to compute the RCS, which can be in turn used to compute the reflected signal.
Hope this helps

i tried same considering a sinusoidally oscillating target whose velocity is as t=0:0.01:0.1; x=2*sin(10*t); splat = phased.Platform([0; 0; 0],[x; 0; 0]);
