AbstractWe propose demonstration of a bistatic HF radar to map vector currents, current shear, and wind vector fields using a multiple-frequency bistatic HF radar capability currently under development. The proposal leverages on our ongoing work in bistatic HFdigital transceiver development for Office of Naval Research, our development of a ship RCS measurement radar for ONR/ NSWC on the west coast, and our two-site bistatic experimental site being developed at the mouth of the Chesapeake Bay. The bistatic HFradar would take advantage of the new transceiver's programmable digital frequency switching to cover a range of 3-30 MHz for current shear, and as a bi-product, ship target classification. Bistatic looks offer an enhanced classification and trackingcapability over monostatic. Algorithms recently developed by Vesecky (IGARSS '02) indicate that wind field vector maps can be derived from current shear estimates. We intend to use this algorithm in conjunction with bistatic radar data, requiring only asingle receive antenna array. This program would result in additional capabilities not available on existing commercial HF current mapping radars, at a lower price due to new digital receiver technology. The potential for dual use for ship tracking andclassification provides an inexpensive approach to maritime traffic control, both for civilian and military applications.
