phased array system toolbox - target velocity

How to simulate a non constant velocity moving target in the toolbox examples

Answer 1

[Honglei Chen]

You can update the velocity at each simulation iteration to mimic different trajectories. Below is an example for circular trajectories:

T = 1;
myPlatform = phased.Platform('Velocity',[1;0;0]);
N = 360;
pos = zeros(3,N);
vel = zeros(3,N);
for m = 1:N
    [pos(:,m),vel(:,m)] = step(myPlatform,T);
    v = [cos(m*pi/180);sin(m*pi/180);0];
    myPlatform.Velocity = v;
end
plot(pos(1,:),pos(2,:))

thankyou Mr. Honglei Chen

Sir, how to simulate the 2d esprit in phased array toolbox

[Honglei Chen]

2D ESPRIT is currently not supported.

Sir, how to see the target's path in the spectrogram,i.e how to see the doppler changes of a target in the spectrogram

[Honglei Chen]

You should be able to just call spectrogram on the received signal. If you are using pulsed radar, then you may need to use slow time data.
