X-Band Sea-Return Measurements
Abstract
Measurements with an X-band system show that sea return follows a law between an inverse square and inverse cube with range, and between zero end the first power with poise duration, tending toward ths former set of conditions with shorter range, steeper incidence, and longer pulses. Sea return in surface radar follows closely the latter limits; the return for high-angle radar-controlled missiles approaches the former. The maximum difference in sea return between vertical and horizontal polarization is approximately 10 db, with about the same maximum difference for different headings. Vertical polarization and upwind headings give the greatest return.
