Path: Link/Radar
% Solves the radar equation. Can compute range or power. This function assumes
that the losses are not functions of wavelength and that the target area is
a flat plate. Lambda is a scalar. The radar is assumed to be monostatic.
Has a built in demo and will plot if no arguments are specified.
There are several options. You can enter an RCS data structure or use the
RCS as d.sigma. You can enter receive and transmit antenna gains or aperture
areas.
