Abstract : The patent describes a sea state analyzer which samples sea clutter video from a selected range at the radar pulse repetition rate and passes the sample through an active filter to provide ocean wave analog voltage signals which are recorded. Circuitry is described which derives from the analog voltage signals and from clock signals, the average wave time period for waves of each group having a predetermined number of waves. One digital display shows the average for the last group computed while another shows the average being developed for a current group.
