Hyperbolic-FM (CHYPE)

Abstract

The report investigates a hyperbolic frequency modulation technique that is doppler invariant. This doppler invariant property assures its usefulness in both the realms of acoustic echolocation and radar. Bat echolocation techniques are discussed and are shown to be surprisingly analogous to current radar techniques. Spectral characteristics of the compressed hyperbolic-FM are examined with respect to its pulse compression capability in extremely high velocity target environments and is shown to be superior to the conventional linear-FM. Matched filtering is simulated via an 11-bit Fast Fourier Transform.
