RADAR SYSTEM AND TRANSMISSION APPARATUS THEREFOR
First Claim
1. A transmission apparatus for a radar system, comprising:
- a signal generator configured to generate a first signal;
a phase adjuster including a plurality of input ports and at least one output port, the phase adjuster being configured to generate a second signal by adjusting a phase of the first signal according to an input port through which the first signal is transmitted among the plurality of input ports, and to output the generated second signal to an antenna unit; and
a port selector configured to select at least one of the plurality of input ports of the phase adjuster according to an identification code and to transmit the first signal through the selected input port so that a transmission signal radiated through the antenna unit is phase inverted or formed in a pattern corresponding to the identification code.

Abstract
The present disclosure relates to a radar system and a transmission apparatus therefor, including a signal generator for generating a first signal; a phase adjuster configured to include a plurality of input ports and at least one output port, to generate a second signal by adjusting the phase of the first signal according to an input port through which the first signal is transmitted among the plurality of input ports, and to output the generated second signal to an antenna unit; and a port selector configured to select at least one of the plurality of input ports of the phase adjuster according to an identification code and to transmit the first signal through the selected input port so that a transmission signal radiated through the antenna unit is phase inverted or formed in a pattern corresponding to the identification code, so that interference by the other radar system can be minimized, and the accuracy, reliability and frequency efficiency of the radar system can be improved.

8. A radar system comprising:
-
an antenna unit in which a plurality of feeding elements are arranged; a transmitter configured to generate a first signal, adjust a phase of the first signal in response to an identification code to generate a second signal, and to output the second signal to the antenna unit; a receiver configured to pre-process a receiving signal received through the antenna unit and to filter the receiving signal based on the identification code to extract a reflection signal reflected from a target; and a signal processor configured to transmit the identification code to the transmitter and the receiver and to analyze the reflection signal to acquire information about the target. - View Dependent Claims (9, 10, 11, 12, 13)
