Title: Innovations of Alexej Namenas in Underwater Detection Technology

Introduction

Alexej Namenas is a notable inventor based in Kiel, Germany. He has made significant contributions to the field of underwater detection technology. His innovative work focuses on sonar methods that enhance the detection and determination of the position and speed of objects underwater.

Latest Patents

Namenas holds a patent for a sonar method for detecting and/or determining the position and/or speed of objects underwater in a specified region. This patent describes a sonar assembly and receiving unit that utilizes orthogonality of Doppler-shifted transmission sequences. The method involves generating a transmission sequence, spreading it for possible Doppler shifts, and outputting it via transmission elements. By carefully choosing the transmission sequence, the spread versions become orthogonal to each other, enabling MIMO signal processing. If one of the assumed spreads matches the speed of an object, it cancels out to form the original transmission signal. This innovative approach allows for the binary detection of an object's presence with minimal computational effort at the receivers.
