ABSTRACT:
A method and apparatus for converting a plan position indicating (PPI) radar image signal into a raster-type video signal and for broadcasting the radar image over an area scanned by the radar beam, where it can be received by a craft traveling within said area. Means are also provided on board each craft for indicating the position of the craft on said image. The PPI radar image signal is first converted to a digital form and stored in a memory unit; then extracted from the memory unit in a format compatible with the television raster display system. The radar image is broadcasted in its PPI form and converted on-board the craft. Means are provided on the crafts for synchronizing the radar image signal with an enhancing signal generated every time the radar beam sweeps over the corresponding crafts.
