Paper Abstract

A frequency versus timedelay (FVTD) technique is introduced to acquire unknown parameters of received chirp signals. This technique can precisely determine a single chirp clearly distinguish completely overlapped upchirp and downchirp and is also capable of realizing various overlapped multiple chirp signals. The basic implementation concept of this approach is relatively simple. We first employ a bank of bandpass filters to noncoherently process the incoming chirps. The filtered and sampled signals are then shifted into a set of frequency time and power distribution sequences which provide enough information for acquiring the unknown parameters of the received chirp signals. Examples and figures are used to illustrate this procedure.
