MICROWAVE PROPAGATION

THIS PROPOSAL ADDRESSES PHASE I OF AN EFFORT TO PROVIDE COMPREHENSIVE QUANTITATIVE MEASUREMENTS OF MICROWAVE PROPAGATION AT LOW ALTITUDES (I.E., BELOW SEVERAL HUNDRED FEET) ABOVE THE SURFACE OF THE OCEAN. THE OVERALL OBJECTIVE OF THE EFFORT IS TO PROVIDE EXPERIMENTAL DATA FOR USE IN THE VERIFICATION OF EXISTING COMPUTER PROGRAM MICROWAVE PROPAGATION MODELS. THE PROPOSED APPROACH DRAWS UPON AN EXISTING METRATEK RADAR SYSTEM THAT HAS PREVIOUSLY BEEN USED BY METRATEK TO PERFORMTHE SAME KIND OF MEASUREMENT. THIS SYSTEM HAS A UNIQUE WAVEFORM THAT WILL BE EXPLOITED FOR THE FIRST TIME IN THE PROPOSED EFFORT TO PROVIDE A MEASUREMENT CAPABILITY THAT WILL GREATLY EXPAND THE DETAILED KNOWLEDGE OF PROPAGATION IN OCEANIC DUCTS.
