The paper explains the process for obtaining ocean variables using one band X radar located ashore. The system includes one algorithm for selecting a sea clutter area with required information to calculate sea variables such as direction, period and significant height of the waves. The research enhanced reported algorithms to extract those variables by including filtering stages. The system has 10% maximum error compared to an in situ sensor. The results motivate the usage of radar ashore for swell monitoring with direct application in coastal erosion studies.
