Claim:
1. A method for detecting a vehicle intrusion, the method comprising: a first signal transmission process for alternately transmitting a first signal of a waveform through a first transmission module and a second transmission module at a predetermined period; a first intrusion determination process for analyzing a reflected wave received in response to the transmitted first signal to determine whether the intrusion occurred; a second signal transmission process for transmitting a second signal of a pulse waveform, upon detecting the intrusion as a result of the first intrusion determination process; a second intrusion determination process for analyzing a waveform of a reflected wave received in response to the transmitted second signal to determine whether the intrusion occurred; and transmitting a predetermined alarm message indicating that the intrusion occurred upon detecting the intrusion as a result of the second intrusion determination process.
