For a simple pulse, the matched filter output is a triangle function, which
exhibits no sidelobes. Thus, sidelobe reduction is not an issue for that waveform

and it will not be further discussed. For the LFM pulse, there are two basic
approaches to delay sidelobe reduction: shaping the receiver frequency
response, and shaping the waveform spectrum.

4.7.1 Matched Filter Frequency Response Shaping
Recall from finite impulse response (FIR) digital filter design that to reduce
