    Abstract: A method and apparatus for detecting objects around a vehicle, comprising a plurality of microwave-transceiver sensors for transmitting microwave signals to reflect off objects around the vehicle. The reflected signals are received and passed to a control unit for comparing the received signal to a transmitted signal to determine whether a detected object constitutes a threat to the moving vehicle. An alarm means is connected to the control unit and activates upon the receipt of an alarm signal when the control unit determines a detected object constitutes a threat to the vehicle.
