Chirp in radar

WebAbstract: A new radar technique has been developed that provides a solution for the conflicting requirements of simultaneous long-range and high-resolution performance in … WebChirp waveforms are commonly used in automotive radar and other sensor applications to provide the required information for calculating range and Doppler velocity of objects in a scene from the radar returns. An example is a frequency modulated continuous wave (FMCW) radar, which transmits a sequence of chirps within a frame as shown in Figure 1.

A Comparison of Chirp Diversity and Pulse Doppler 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 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.
