Why does applying Fourier Transform on point Spread Function yield h(t) which is complex-valued
The Fourier transform doesn't move only from time to frequency (or space etc.), it moves between these domains. The only difference between the Fourier transform and its inverse is a sign in the expon …

Frequency response of FIR (MTI delay line canceller) with non constant period
If you mean that you want a time-varying delay then the whole system becomes time-varying, which means that there is no such thing as a frequency response in the conventional sense. Only linear time-i …

Time-Bandwidth Product
Note that these definitions of effective duration and effective bandwidth are only useful for very specific signals, namely for (real-valued) low-pass signals that are even and centered around $t=0$. …

Minimizing Time Sidelobes with Pulse Compression
You could define a weight sequence $w(n)$ that weighs the error differently for different time indices $n$:
$$\epsilon^2=\sum_{n=0}^{N+K-2} w(n)\big|d(n)-z(n)\big|^2\tag{1}$$
Samples that are too la …
