Patent ID: 8295393

Claim:
A pulse signal transmitting/receiving device, comprising: a signal generating module for generating a transmitting signal including an amplitude-modulated chirp signal having a frequency that changes, and a reference signal including a chirp signal having a frequency that changes; a transmitting module for transmitting a pulse having approximately the same waveform as that of the transmitting signal; a receiving module for receiving an echo signal that is the transmitting pulse reflected from a detection target object; a compensating module for extending a dynamic range of the echo signal received by the receiving module; and a pulse compressing module for outputting a pulse-compressed echo signal, wherein the pulse compression is performed by a correlation calculation between the echo signal having the dynamic range extended by the compensating module, and the reference signal, wherein the compensating module has input/output characteristics that are determined based on a system function G(f) obtained by dividing a Fourier transform X(f) of a signal x(t) similar to the reference signal by a Fourier transform S(f) of a signal s(t) similar to the transmitting signal.
