Zusammenfassung:	PROBLEM TO BE SOLVED: To solve a problem wherein a method of discriminating a radar signal from a communication signal is required to avoid an interference between a radio network and a radar system. SOLUTION: A radio network system includes a correlation module, an automatic gain control module, and a control module. The correlation module finds a correlation in prescribed portion of a radio frequency (RF) signal, and generates a correlation signal based thereon. The automatic gain control (AGC) module generates a gain control signal based on the RF signal. The control module determines selectively whether the RF signal is the radar signal or not, based on the correlation signal and the gain control signal. COPYRIGHT: (C)2007,JPO&INPIT
