create matlab program to track 3 targets using an lfm waveform in matlab

main.m
fs = 1e6; % Sampling frequency
T = 1/fs; % Sampling period
fStart = 20e3; % Start frequency of the LFM waveform
fStop = 80e3; % Stop frequency of the LFM waveform
t = 0:T:0.1; % Time vector from 0 to 0.1 second
lfmWaveform = chirp(t, fStart, t(end), fStop, 'linear');
