FIGURE 1.21 (a) Linear FM waveform modulation function, showing an
increasing instantaneous frequency. (b) Output of the matched filter for the LFM
waveform of (a).
The matched filter is by definition a filter in the radar receiver designed to
maximize the SNR at its output. The impulse response of the filter having this
property turns out to be a replica of the transmitted waveform’s modulation
