    Abstract: An apparatus for testing the performance of a synthetic aperture radar is provided. The apparatus for testing the performance of a synthetic aperture radar includes: a three-axis motion platform that is coupled to an antenna and driven in roll, pitch, and yaw directions so as to reproduce motion components generated from a pointing plane of the antenna; a target simulator configured to reproduce a ground target; and a system simulator that allows the three-axis motion platform and the target simulator to work in conjunction with each other in real time, and controls the three-axis motion platform and the target simulator. Here, the three-axis motion platform may include a three-axis driver that determines the attitude of the three-axis motion platform, based on position and speed information received from the system simulator. The target simulator may include a target modulator that adjusts the amplitude of an output signal, performs range and phase delays, and reproduces a Doppler component, based on simulation target information received from the system simulator.

    Abstract: Provided is a T-DMB receiver and receiving method using a human body as an antenna. The T-DMB receiver includes: an electrode making contact with a human body; a low frequency amplifier receiving via the electrode a current flowing through the human body due to a DMB broadcasting signal emitted by a terrestrial relay station and amplifying the received current; and an impedance matching circuit located between the electrode and the low frequency amplifier and matching an impedance of the human body with an impedance of the low frequency amplifier. Accordingly, a T-DMB receiver easy to carry without a separate antenna can be implemented.

    Abstract: Provided is a communication apparatus having a human body contact sensing function and method. The apparatus includes: an electrode that comes in contact with the human body; a contact sensor coupled to the electrode that instructs the CPU to perform an initial operation if contact with the human body is sensed; and a data processing unit that receives a control signal from the CPU to select whether to transmit or receive data, and performs a transmitting or receiving operation according to the control signal. To reduce power consumption in a stand-by state before body contact is made when using a human body as a communication medium, a human body contact sensor is included to minimize power consumption of a micro processing unit and a transmitter/receiver circuit until contact occurs. Minimizing power consumption when in a stand-by mode by using a contact sensor with low power consumption extends stand-by time.
