How to know which platform is associated with which object in Phased array toolbox?

Hi:

I was just looking at some examples of simulating radars using Phased Array Systems toolbox. However I am unable to understand that how can I know which platform is associated with which object. For example in the code below, I have tried to define one antenna, three targets and then four platforms. How can I be sure that which platform is associated with which object?

    fc = 10e9;

    hant = phased.IsotropicAntennaElement('FrequencyRange',[5e9 15e9]);
    htarget1 = phased.RadarTarget('MeanRCS',1.6, 'OperatingFrequency',fc);
    htarget2 = phased.RadarTarget('MeanRCS',2.2, 'OperatingFrequency',fc);
    htarget3 = phased.RadarTarget('MeanRCS',1.05, 'OperatingFrequency',fc);

    hantplatform     = phased.Platform('InitialPosition',[0; 0; 0], ...
        'Velocity',[0; 0; 0]);
    htargetplatform1 = phased.Platform('InitialPosition',[1; 1; 1], ...
        'Velocity',[150;100;0]);
    htargetplatform2 = phased.Platform('InitialPosition',[2; 2; 2], ...
        'Velocity',[0; 0; 0]);
    htargetplatform3 = phased.Platform('InitialPosition',[3; 3; 3], ...
        'Velocity',[0; 0; 0]);

Are the objects being associated with the platforms with respect to the order in which they appear?
