Comparison of Elevation Angle Measurement Techniques over the Sea

RÉSUMÉ

Experimental results of research of special elevation angle measurement technique of a low-altitude radiation source in natural conditions over the sea surface are obtained and analyzed: an off-axis monopulse technique and a symmetrical patterns technique. The measurements are executed in centimeter and millimeter wave range on the path from hundreds of meters up to several kilometers at sea state 3. Comparison of their efficiency with the now widely used monopulse sum-difference amplitude technique is carried out. The results of experimental research are added with the computer simulation. Conclusions about efficiency of the tested techniques in concrete conditions are made. It is shown that the off-axis technique has a number of advantages over other technique practically in all conditions of test performance.
