Title:
PULSE RADAR DEVICE
Document Type and Number:
Japanese Patent JP3925068
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a pulse radar device needing only short signal transmission time for one composite band processing even when a relative distance R between the pulse radar device and a target is long.
SOLUTION: This pulse radar device is provided with a fixed initial phase frequency synthesizer generating a locally oscillating signal for transmission of a predetermined frequency and an initial phase per pulse repetition period of a positive integral multiple of an inverse number of a predetermined step frequency interval, a frequency calculator determining frequency information of a reception wave using predetermined relative distance information with the target, and a fixed initial phase frequency synthesizer generating a locally oscillating signal for transmission of a frequency corresponding to a frequency of the reception wave in a predetermined phase by using the frequency information of the reception wave determined by the frequency calculator.
