Abstract
A collision alerting and avoidance system is presented herein. The system comprises at least one antenna array disposed on a structure on the ground and at least one transmitter/receiver probe coupled to the antenna array. The transmitter/receiver probe operates in a transmit mode to transmit electromagnetic waves and in a receive mode to receive an echo signal reflected from an obstacle in the area of an aerial vehicle. The system also comprises at least one transmitter/receiver module coupled to the transmitter/receiver probe. The transmitter/receiver module operates in a transmit mode to produce electromagnetic waves for transmission and in a receive mode to receive the echo signal. The system also comprises a processor coupled to the transmitter/receiver module. The processor controls transmission of the electromagnetic waves from the antenna array and processes the echo signal to provide an output signal containing information regarding the obstacle.
