Chirp frequency response
WebThe 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. Furthermore, the process offers … WebSep 1, 2010 · Sept. 1, 2010. Evaluation Engineering. Chirp measurements in radar applications are used to determine the quality of transmitted pulses. The primary quality indicators revolve around the need for ...

WebFeb 26, 2010 · For example, you can create a frequency sweep (chirp) using the frest.Chirp command or create a random signal with the command frest.Random . You can also use a timeseries object to specify a custom input signal. 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 more The basic definitions here translate as the common physics quantities location (phase), speed (angular velocity), acceleration (chirpyness). If a waveform is defined as: See more A chirp signal can be generated with analog circuitry via a voltage-controlled oscillator (VCO), and a linearly or exponentially ramping control voltage.
