[mw_shl_code=applescript,true]function[delta_R] = range_resolution(var)
% thhis function computes radar resolution in meters
%Inputs:
%var can be either
%var ==Bandwidth in HZ
%var ==Pulse width in seconds
%Outputs
%delta_R ===range reslution in meters;
%Bandwidth may be euual to (1/pulse width) ==>indicator = seconds;

c = 3.e+8;% 光速
indicator=input ("Enter 1for var == Bandwidth ,OR 2 for vcar == Pulse width\n");

    case 2
