Radiation Analysis Of Buoy Antenna In Typical Sea Conditions

In the marine emergency rescue, Emergency Position Indicating Radio Beacons (EPIRB),GPS and Search and Rescue Radar Transponder (SART) is mainly responsible for important functions to send rescue ships and aircraft direction finding and range information. Under different sea conditions,especially in adverse sea conditions,the merits of the antennas performance parameters is directly related to the success and timeliness of the rescue,so the research is very important.Based on the buoy antenna problem actually existing in the typical sea state, I mainly to do the following work:First, because of the antenna prolonged storage and working environment in the sea by the wind, rain, snow, invasion of exposure, salt, fog and haze, water and other harmful factors,it need to install an external antenna radome. And analyze the impact of the radome material,shape, thickness of the three factors of radiation of three kinds of antennas.Then, according to the principles of fluid dynamics and wave spectrum PM, analyze buoy pitching motion in the vertical direction and under the effect of wave action. Generate three-dimensional graphics simulation of the sea waves according to PM spectrum. Use Methods of PO to simulate pattern of three kinds of antennas in typical heights and sea conditions. Then get affect the height of the antenna radiation effectiveness placed in different sea conditions.Finally, analyze the role of scale buoy in the horizontal direction and under the waves rolling motion. Use Methods of PO to simulate pattern of three kinds of antennas in typical heights, typical angles and typical sea conditions. Then get affect the angle of the antenna radiation effectiveness placed in different sea conditions...
