Pulse radar system
First Claim
1. A pulse radar system comprising:
- a pulse output circuit outputting a periodic transmission pulse and a gate pulse, the gate pulse having a cycle which is a rational multiple of a cycle of the transmission pulse and is different from the cycle of the transmission pulse;
a transmission circuit generating a transmission pulse wave based on a transmission pulse from the pulse output circuit, and outputting the transmission pulse wave generated;
a transmission antenna radiating a transmission pulse wave from the transmission circuit;
a reception antenna receiving a reception pulse wave, the reception pulse wave being radiated from the transmission antenna as a transmission pulse wave and reflected from an object;
a reception circuit demodulating the reception pulse wave from the reception antenna and outputting a reception pulse; and
an extracting circuit extracting a reception pulse, which is synchronized with a gate pulse from the pulse output circuit, from among reception pulses from the reception circuit, and outputting the reception pulse extracted.

Abstract
A pulse radar system includes: a pulse output circuit that outputs a periodic transmission pulse and a gate pulse having a cycle which is a rational multiple of a cycle of the transmission pulse and is different from a cycle of the transmission pulse; a transmission circuit that generates and sends a transmission pulse wave based on a transmission pulse from the transmission circuit; a transmission antenna that radiates a transmission pulse wave from the transmission circuit; a reception antenna that receives a reception pulse wave reflected from an object in transmission pulse waves from the transmission antenna; a reception circuit that demodulates a reception pulse wave from the reception antenna and outputs a reception pulse; and an extracting circuit that extracts and outputs a reception pulse synchronizing with a gate pulse from the pulse output circuit, among reception pulses from the reception circuit.
