PULSE WAVE RADAR DEVICE
First Claim
Patent Images
1. A pulse wave radar device comprising:
- a transmitting signal generation circuit for generating a transmitting signal in which a distance-measuring signal and a user data signal are multiplexed one on the other;
an RZ code conversion circuit for generating an RZ propagation signal obtained by RZ-converting the transmitting signal from the transmitting signal generation circuit into a RZ code having a predetermined pulse width;
a transmitting circuit for transmitting a transmitting wave obtained by intensity-modulating the RZ propagation signal from the RZ code conversion circuit at a local oscillation frequency;
a transmitting antenna for emitting the transmitting wave sent from the transmitting circuit;
a receiving antenna for receiving a receiving wave reflected by a target; and
a receiving circuit for intensity-demodulating the receiving wave into RZ propagation signal by detecting the receiving wave from the receiving antenna.

Abstract
A pulse wave radar device transmits at a constant period a transmitting signal in which identification data for identifying of pulse wave radar devices is added to a distance-measuring signal so that any other pulse wave radar device can identify a receiving wave reflected by a target owing to a transmitting wave that itself has transmitted.
