    %% Maximum Detectable Range for a Monostatic Radar
% Assume that the minimum detectable SNR at the receiver of a monostatic
% radar operating at 1 GHz is 13 dB. Use the radar equation to determine
% the maximum detectable range for a target with a nonfluctuating RCS of
% $0.5m^{2}$ if the radar has a peak transmit power
% of 1 MW. Assume the transmitter gain is 40 dB and the radar transmits a
% pulse that is 0.5μs in duration.
tau = 0.5e-6;
G = 40;
RCS = 0.5;
Pt = 1e6;
lambda = 3e8/1e9;
SNR = 13;
maxrng = radareqrng(lambda,SNR,Pt,tau,'rcs',RCS,'gain',G)

% The maximum detectable range is approximately 345 km.
