| Definition | A coherent on receive marine radar system, designed for the observation of surface waves and currents. It is based on the radar scanner SU70-14E from GEM Electronica, which operates in the X-band (9.4 GHz) frequency range, with a peak power of 12 kW. The radar scanner was modified by adding the followingcomponents: linear amplifier, analogue to digital converter (ADC), control board and a step motor with an angular position transmitter. The radar is controlled by a computer. It features an antenna which can be used in either static or rotation modes. In static mode the antenna is oriented in a pre-selected fixed direction. In rotation mode the antenna performs 360 degrees azimuthal scans of the ocean surface at a rotation speed up to 36 rpm. The system can also be used with either vertical or horizontal polarisation antennae within a frequency band of 9410 MHz +/- 50 MHz. It uses a short pulse (50 ns) representing a range resolution of 7.5 m and a pulse repetition frequency up to 2 kHz. | |
