Title: Petri Haapanen: Innovator in Radar Technology
Introduction
Petri Haapanen is a notable inventor based in Vantaa, Finland. He has made significant contributions to the field of radar technology, holding 2 patents that showcase his innovative approach to solving complex problems in weather radar systems.
Latest Patents
Haapanen's latest patents include a "Simultaneous Dual Polarization Radar System with Pedestal Mounted Receiver." This invention relates to a method and apparatus for the simultaneous transmission of horizontal and vertical channels in a dual polarized weather radar. The design places the receiver, duplexer, and polarizer equipment strategically above the azimuth rotary joint but below the elevation rotary joints. This configuration allows for precise calibration of the elevation rotary joints and associated signal paths using a low power signal on the radar's operating frequency.
Another significant patent is the "Method and Apparatus for Pointing the Beam of a Wind Profiler." This invention involves a stationary antenna matrix with several individual antenna elements. The method feeds an input signal to the antenna matrix and adjusts the phase of the input signal for each antenna element to accurately point the beam of the profiler. The invention utilizes separate feeder lines for each beam and controls phase differences with hybrid coupler elements.
