caf_verilog.caf.simple_caf(x, y, foas, fs)

Produce values for a surface plot of the Complex Ambiguity Function. This function primarily supports testing values produced via sim_helper, so y is expected to be twice the length of x. The return is the CAF surface and a time delay range normalized by the sampling frequency.

Parameters:

• x – Use x as a reference signal.
• y – Use y as a captured signal.
• foas – Frequency offsets, provided as a list/iterable object.
• fs – Sampling frequency

Returns:

caf_res, dt
