This code is applied for high-speed maneuvering target detection and parameter estimation in the field of radar signal processing.This method first uses second-order KT to eliminate range walk, and uses De-chrip processing to estimate and compensate the target's acceleration, and then uses one-dimensional search to obtain target's fold factor. Finally, the signal energy is focused into the range-Doppler domain.
