PCT No. PCT/EP98/05535 Sec. 371 Date Jul. 20, 1999 Sec. 102(e) Date Jul. 20, 1999 PCT Filed Sep. 1, 1998 PCT Pub. No. WO99/12051 PCT Pub. Date Mar. 11, 1999The invention relates to a method of detecting a radar target, especially a sea target, in the presence of clutter caused by ocean waves in particular. To detect a radar target within a predeterminable region, first a measurement window corresponding to this region is formed in the video range of the radar system, and a frequency distribution is determined for all pulse-height values (amplitudes) within the measurement window. The average value and the standard deviation can be determined from the distribution; from these values, a hit-recognition threshold is determined and used to decide whether a pulse-height value is to be associated with a radar target to be detected.
