Title: Innovations of Le Zheng in Radar Technology

Introduction

Le Zheng is an accomplished inventor based in Monterey Park, CA (US). He has made significant contributions to the field of radar technology, particularly through his innovative patent related to frequency-division multiplexing.

Latest Patents

Le Zheng holds a patent for "Asymmetrical frequency-division multiplexing for radar systems." This patent describes advanced techniques and systems that enhance radar capabilities. The radar system includes multiple transmitters and receivers, along with polyphase shifters and a processor. The transmitters are designed to emit electromagnetic (EM) signals using an FDM scheme. The receivers capture EM signals that are reflected by various objects across multiple channels. The polyphase shifters introduce at least four potential phase shifts, while the processor manages these shifts to create an asymmetrical distribution in the frequency spectrum. This innovative approach allows for the detection of objects using residue estimation and subtraction, thereby supporting numerous simultaneous MIMO channels, increasing the radar system's dynamic range, resolving Doppler ambiguities, and providing an efficient processing scheme.
