Latest Patents

One of Tomii's latest patents is the Phased-array antenna device. This innovative device boasts a long operating life without mechanical parts, high spatial resolution, and the capability for microwave observation across broadband and high-frequency ranges. The device performs direct A/D conversion through a band-pass filter (BPF) on an antenna analog signal that has been amplified. It then executes a second cross-spectrum calculation after converting the data into complex frequency information through Fast Fourier Transform (FFT). To detect weak electromagnetic waves, the device conducts repeated second FFTs over extended periods, culminating in data integration.

Another notable patent is the Measurement data processing device. This system includes an antenna with predetermined directivity and a processing device that enhances the spatial resolution of measurement data received from the antenna. It features multiple multipliers that combine measurement values, which represent the signal intensity of microwave output from a radiometer, with weighting coefficients to produce elements of a weighted vector. An integrator then processes these multiplication results, modifying the accuracy of the corrected sensitivity function to reduce integrated values in both positive and negative regions surrounding the target antenna's sensitivity distribution.
