Introduction

Hideki Marui is a notable inventor based in Kawasaki, Japan. He has made significant contributions to the field of radar technology, holding 2 patents that showcase his innovative spirit and technical expertise.

Latest Patents

Marui's latest patents include a weather radar apparatus and a radar return signal processing apparatus. The weather radar apparatus is designed to include an antenna apparatus, a signal processing apparatus, a data converter, a forecasting unit, a state determination unit, and a radar controller. This system radiates a radar pulse and receives a reflection pulse, calculating reception intensity, Doppler speed, and speed width. The data converter processes rainfall intensity and wind direction/speed data, while the forecasting unit generates forecasting data based on this information. The state determination unit then creates an observation sequence, which the radar controller uses to manage the antenna apparatus accordingly.

The radar return signal processing apparatus features a detector, an estimation unit, and an extraction unit. The detector identifies average Doppler frequency, spectrum width, and received power from radar return signals obtained at regular intervals. The estimation unit optimizes a mixed density function by modeling the frequency spectrum, while the extraction unit retrieves information from the radar return signal based on the estimated parameters.
