A PULSE COMPRESSION METHOD FOR CHIRP SIGNAL AND WIRELESS TRANSCEIVER THEREOF

摘要

A pulse compression method for CHIRP signal and a wireless transceiver thereof; pulse compression processing of a cycle C_k has the following steps: analytically obtaining all instantaneous frequency components of instantaneous signals and then isolating out a corresponding amplitude; using storage spaces M_n to store the amplitude and phase of each of the instantaneous frequency components; setting T_n as a length of time from t_n to an end time of the corresponding cycle; calculating T_n according to formula T_n =T-t_n; using another set of storage spaces M_T to rearrange amplitudes of the different instantaneous frequency components; storing the amplitude of each of the instantaneous frequency components in a set of T_n value corresponding storage spaces of M_T space; and accumulating overlapping amplitudes of instantaneous frequency components into another space in the storage spaces M_T.
