FMCW Chirp Configuration for Short, Medium, and Long-Range Radar

WebAbstract: The concept of a new moving target indicator MTI based on the range-doppler coupling properties of chirp, step-chirp, and certain polyphase codes is discussed. The principal feature of the range-doppler coupled MTI is that target blind speeds are eliminated. WebChirp is one of the modulation formats used in most radar systems that can allow fast collection of slow-moving and fast-moving objects.

Why is Chirp Used in Radar?

WebJul 20, 2024 · FMCW Chirp Configuration for Short, Medium, and Long-Range Radar. Radar waveforms are classified into three categories based on the bandwidth of … WebBased on the offset, the chirp rate is calculated. In practice, the cross correlation is always summarized from each range cell and considered as the reference one. Thus, the accurate NPEs of full aperture can be integrated from the chirp rate of each segment after being resampled corresponding to the aperture time. Web1 is a chirp, and 2 is the phase variation due to the stepped variety of the carrier frequency of the signal. Thus, the signal processing is implemented by the fol-lowing two steps: (1) the pulse compression of the chirp at each PRT gives the coarse range proﬁles; (2) the inverse dis-crete Fourier transform (IDFT) of the coarse range proﬁle nottinghamshire geography
