Abstract
Provided is an in-vehicle pulse radar device capable of calculating a distance to a target object based on a delay time between a transmission pulse wave and a received signal. The in-vehicle pulse radar device includes: a reception control unit for controlling passing and blocking of the received signal in synchronization with the transmission pulse wave; a shaping unit for shaping the trailing edge of a pulse wave of the received signal to be delayed; and a sampling unit for sampling the received signal when a predetermined period of time elapses after the reception control unit starts to pass the received signal therethrough.
Claims9
A pulse radar device comprising:
- a conversion means for converting a transmission signal to a transmission pulse wave by use of a predetermined on time and off time;
- a transmission means for transmitting the transmission pulse wave from a transmission antenna toward a target object;
- a reception antenna which receives a signal reflected by the target object;
- calculation means for calculating a distance to the target object based on a delay time between the transmission pulse wave and the signal received by the reception antenna;
- reception control means for controlling passing and blocking of the received signal in synchronization with the transmission pulse wave;
- shaping means for shaping a trailing edge of a pulse wave of the received signal to be delayed;
- and
- sampling means for sampling the received signal when a predetermined period of time elapses after the reception control means starts to pass the received signal therethrough.
