基于matlab GUI界面的雷达仿真代码 具有丰富的参数选项 如目标个数

function [t a phi] = targetsReturn(targets, antenaGain,Amp,t,w,targetsTime,IF_Freq)
% returns the time the pulse returns and the amplitude
    dt = targetsTime-t;

        targetsAngle = atan2(cor(2) , cor(1));
        targetsAngle = mod(targetsAngle-radarAngle+pi,2*pi);
        in = round( (targetsAngle)/2/pi*N );    %finding the antena gain in this angle - I forgot it should be relative angle !!!!!!!!!!!!!!!!!
        in = max(in,1); in = min(in,N);
        a(n) = targets(n).RCS / dist2^2 *   antenaGain(in).^2 * Amp; % here should come the radar formula !
