  2. Orthomode transducer - Wikipedia

    en.wikipedia.org/wiki/Orthomode_transducer

    In the VSAT K u band of operation case, a typical OMT provides a -40 dB isolation between each of the connected radio ports to the feed horn that faces the parabolic dish reflector (-40 dB means that only 0.01% of the transmitter's output power is cross-fed into the receiver's wave guide port). The port facing the parabolic reflector of the ...

    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 ).

    (a) In image processing, periodicity is often subject to projective geometry (i.e. chirping that arises from projection). (b) In this image, repeating structures like the alternating dark space inside the windows, and light space of the white concrete, chirp (increase in frequency) towards the right. (c) The chirplet transform is able to ...

  7. 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.
