1. A method for detecting a first target and a second target, said method comprising the steps of:

  • transmitting a coded pulse signal for scattering by the first and second targets to generate a return signal;

    receiving said return signal;

    applying pulse compression to said return signal to produce a pulse-compressed signal;

    operating on said pulse-compressed signal to identify a point spread function (PSF) corresponding to said first target, said point spread function having a peak and accompanying time-sidelobes;

    subtracting said point spread function from said pulse-compressed signal to generate a residual signal; and

    identifying a peak in said residual signal, said identified peak corresponding to said second target.
