In the high VHF band (152.2 MHz) the Bragg scattering waves on the sea surface have wavelengths of about 1 m. The radar Doppler spectrum of echoes can be heavily modulated by swell in open water, and in the surf zone the effect is enhanced. Under these conditions the Bragg first-order lines are broadened This paper reports on a study to evaluate the integrity of the surface current maps produced by...
