2. Chirp - Wikipedia

   en.wikipedia.org/wiki/Chirp

   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. [1] 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 ...

3. Chirp compression - Wikipedia

   en.wikipedia.org/wiki/Chirp_compression

   The chirp pulse compression process transforms a long duration frequency-coded pulse into a narrow pulse of greatly increased amplitude. It is a technique used in radar and sonar systems because it is a method whereby a narrow pulse with high peak power can be derived from a long duration pulse with low peak power.

4. Sonar - Wikipedia

   Sonar (sound navigation and ranging or sonic navigation and ranging) [2] ... The pulse may be at constant frequency or a chirp of changing frequency ...

5. ANT (network) - Wikipedia

   en.wikipedia.org/wiki/ANT_(network)

   ANT (originates from Adaptive Network Topology) is a proprietary (but open access) multicast wireless sensor network technology designed and marketed by ANT Wireless (a division of Garmin Canada). [1] It provides personal area networks (PANs), primarily for activity trackers. ANT was introduced by Dynastream Innovations in 2003, followed by the ...

6. Chirp spectrum - Wikipedia

   en.wikipedia.org/wiki/Chirp_spectrum

   The Fresnel ripples on a chirp spectrum are very obtrusive, especially when time-bandwidth products are low (under 50, say) and their presence leads to high time sidelobe levels when chirps are subject to pulse compression as in radar and sonar systems. They arise because of the sudden discontinuities in the chirp waveform at the commencement ...

7. Pulse compression - Wikipedia

   en.wikipedia.org/wiki/Pulse_compression

   Pulse compression is a signal processing technique commonly used by radar, sonar and echography to either increase the range resolution when pulse length is constrained or increase the signal to noise ratio when the peak power and the bandwidth (or equivalently range resolution) of the transmitted signal are constrained.
