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,:))

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.
