ABSTRACT:
A terrain imaging apparatus and method for indicating to a user the location and distance of moving objects from a user. A transmitting means transmitts a coherent radiation beam to distant objects and receives back the coherent radiation beam reflected from the objects. A communicating means indicates the direction and distance of objects moving in that field relative to the user by determining the distances to the objects from the transmitting and receiving means and the direction in which the beam is directed to synthesize a vector field image of the terrain based on a set of direction measurements and corresponding range measurements and indicating the direction the user is facing relative to the terrain image.
