Coherent Processing of Up/Down Linear Frequency Modulated …

Webwide bandwidth waveforms, and thus the need for stretch processing, is “overkill” for tracking. Generally speaking, bandwidths of 1s to 10s of MHz are sufficient for tracking One of the most common uses of wide bandwidth waveforms, and stretch processing, is in discrimination, where we need to distinguish individual scatterers on a target. WebChirp is one of the modulation formats used in most radar systems that can allow fast collection of slow-moving and fast-moving objects. Chirp is better known in the lasers community as pulse compression, a form of time-dependent phase modulation that generates a change in the instantaneous frequency of an emitted pulse.

"The spectrum of a chirp pulse describes its characteristics in terms of its frequency components. This frequency-domain representation is an alternative to the more familiar time-domain waveform, and the two versions are mathematically related by the Fourier transform. The spectrum is of particular interest when pulses are subject to signal processing. For example, when a chirp pulse is compressed by its matched filter, the resulting waveform contains not only a mai… " - Chirp waveform
