Stepped Frequency Modulated Waveform Continuity issues [duplicate]
I want to generate a stepped frequency modulated waveform (SFMW), similar to a linear frequency modulated chirp.
While approaching this, I wanted to consider the issue that there should be some contin …

Time shifting a signal in python
I am currently modeling FMCW (linear FM) and SFCW (stepped FM) chirps in python. For my project, I need to simulate those signals as a transmit chirp and a received one, scattered from point targets a …

Synthetic Aperture Radar model: Ground reflected energy
My question is related to a theoretical part of the book: Digital Processing of Synthetic Aperture Radar Data, Algorithms and Implementation by I.G. Cumming et al. [Chapter 4. … (\tau)$, "the reflected energy at any illumination instant is a convolution ..." as:
$$
s_r(\tau) = g_r(\tau) \ast s_{pul}(\tau)
$$
An example is given for a point target at a distance $R_a$ from the radar …
