Abstract
A near object detection (NOD) system includes a plurality of sensors, each of the sensors for providing detection coverage in a predetermined coverage zone. Each of the sensors includes a transmit antenna for transmitting a first RF signal, a receive antenna for receiving a second RF signal and a means for sharing the target data between each of the plurality of sensors in the NOD system.
