Patent ID: 7706452

Claim:
A receiver comprising: a reception front-end for receiving a plurality of pulse signals including at least a first pulse signal and a second pulse signal as a reception signal, wherein a pulse sequence generating time of the second pulse signal is longer than a pulse sequence generating time of the first pulse signal; a delay circuit for generating a delay signal by delaying a reception front-end output signal output from the reception front-end; and a delay pulse composition circuit for combining the delay signal with the reception front-end output signal, wherein a delay time given to the reception front-end output signal by the delay circuit is longer than the pulse sequence generating time of the first pulse signal, and is shorter than the pulse sequence generating time of the second pulse signal; wherein the reception front end comprises a first antenna which receives both of the first pulse signal and the second pulse signal and a second antenna which receives only the second pulse signal; wherein the second antenna is narrower in a reception frequency band than the first antenna; wherein a reception signal received at the first antenna is output to the delay pulse composition circuit, and a reception signal received at the second antenna is output to the delay circuit; and wherein the delay pulse composition circuit combines the delay signal output from the delay circuit with the reception front-end output signal output from the first antenna.
