WebAug 18, 2008 · Modern radars using frequency chirp modulation present many measurement challenges to the designer and system engineer. Complex test systems involving many instruments have traditionally been required to validate radar performance. 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.
