E:\Merlin\Projects\Technical\KH\FCC\Functional_Description.txtMonday, November 22, 2010 10:50 The solid state radar sub-system with patented SharpEyeTM technology is a “range unambiguous” X-Band radar (9.3 to 9.5GHz) utilising a coherent receiver, pulse compression and Doppler processing techniques to provide sub-clutter visibility of targets. The radar is designed to exceed the IALA recommendations for a VTS radar sensor. The high technology, low cost design makes the radar ideal for all three capability categories defined by IALA and where the detection of very small vessels is of paramount importance for safety, search and rescue and security reasons. -1-

Tune up procedure Explanation SharpEye radar is a solid state device and will transmit on the frequency selected. There is no requirement for tuning and as such has no tuning procedure. By Kelvin Hughes

Both lines were observed with the DUT transmitting. The bandwidth of the spectrum analyzer was 10 kHz with an appropriate sweep speed. Bandwidth 20 dB: The measurements were made with the spectrum analyzer's resolution bandwidth (RBW) = 1 MHz and the video bandwidth (VBW) = 3 MHz and the span set as shown on plot. Power Output: The RF power output was measured at the antenna feed point using a peak power meter. Antenna Conducted Emissions: The RBW = 100 kHz, VB…
