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