Why is Chirp Used in Radar?

A chirp is a signal in which the frequency increases (up-chirp) or decreases (down-chirp) with time. In some sources, the term chirp is used interchangeably with sweep signal. It is commonly applied to sonar, radar, and laser systems, and to other applications, such as in spread-spectrum communications (see chirp spread spectrum).

WebFor accurate motion compensation (MOCO) in airborne synthetic aperture radar (SAR) imaging, a high-precision inertial navigation system (INS) is required. However, an INS is not always precise enough or is sometimes not even included in airborne SAR systems. In this paper, a new, raw, data-based range-invariant motion compensation approach, which … WebBased on the offset, the chirp rate is calculated. In practice, the cross correlation is always summarized from each range cell and considered as the reference one. Thus, the accurate NPEs of full aperture can be integrated from the chirp rate of each segment after being resampled corresponding to the aperture time. shutterfly wedding photo bookWebJan 1, 2003 · The stepped-frequency radar signal is revisited.
