摘要
In time-space domain, the multicomponent chirp signal is deoomposed into several monocornponent chirp signals. Based on H∞ filter, dechirping for the monocornponent chirp signal is achieved. When date length of the multicomponent chirp signal is short and SNR is low, this approach is applicable. It is insensitive to the exact knowledge of the statistics of the unknown disturbance and noise. Simulation results are presented to show the validity of the approach.
