Chirp algorithm

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). This signal type is biologically inspired and occurs as a ph… WebOct 19, 2024 · GitHub - achael/eht-imaging: Imaging, analysis, and simulation software for radio interferometry achael eht-imaging main 5 branches 11 tags Code achael Merge pull request #154 from achael/dev 1ca33d0 on Oct 19, 2024 2,078 commits .github/ ISSUE_TEMPLATE Update issue templates 4 years ago arrays added …
