PRECISION POSITION MEASUREMENT FOR SURFACE SHIPS UTILIZING SHORT PULSE MICROWAVE TRANSMISSION

Trilateration computations of radar measurements made between surface ship-based interrogator-responsors and shore-based transponders can be used to obtain better than 2-ft positional accuracy at line-of-sight ranges of the order of 5 mi. Use of nanosecond pulses provides elimination of the usual range errors caused by multipath reflections from sea surface and ship's superstructure. A description of currently available hardware to accomplish these positional accuracies is presented.
