Title: Innovations of Wen-Sheng Cheng
Introduction
Wen-Sheng Cheng is a notable inventor based in Taipei, Taiwan. He has made significant contributions to the field of radar technology, holding a total of four patents. His work focuses on enhancing radar signal processing systems and improving detection methods.
Latest Patents
One of his latest patents is a radar system with a self-interference cancelling function. This innovative radar signal processing system includes an analog front end (AFE) processor, an analog to digital converter (ADC), an adaptive interference canceller (AIC), and a digital to analog converter (DAC). The AFE processor receives an original input signal and generates an analog input signal. The ADC converts the analog input signal to a digital input signal. The AIC generates a digital interference signal by performing an adaptive interference cancellation process according to the digital input signal. The DAC then converts the digital interference signal to an analog interference signal. Finally, the analog interference signal is fed back to the AFE and cancelled from the original input signal in the AFE processor, reducing the interference from a nearby transmitter during the front end process.
Another significant patent is the range Doppler angle detection method and device. This method involves receiving a first sensing signal and a second sensing signal. It performs 1D Fast Fourier Transform (FFT) and 2D FFT on the first sensing signal to calculate a first 2D FFT map. Similarly, it processes the second sensing signal to create a second 2D FFT map. The method then picks one column from each 2D FFT map according to a given Doppler index and performs a 3D FFT on these columns to calculate a range Doppler angle. This approach effectively reduces the computational load of the gesture recognition function.
