Title: Per Atle Våland: Innovator in Radar Technology

Introduction

Per Atle Våland is a notable inventor based in Oslo, Norway. He has made significant contributions to the field of radar technology, holding a total of 3 patents. His work focuses on enhancing radar systems for improved detection capabilities.

Latest Patents

One of his latest patents is titled "Method and radar system for coherent detection of moving objects." This invention provides a coherent radar system that modifies standard non-coherent radar without Moving Target Indication. Typical radars in this category are navigation radars, which are mass-produced using low-cost components. The invention utilizes a magnetron in the transmitter, which is a random phase device. The received signal is extracted just before the amplitude detection process, where phase information is typically lost. It is then digitized using an analogue to digital converter, allowing for coherent detection based on the correlation between the transmitted pulse and the received signal.

Another significant patent is the "Digitizer arrangement." This invention involves a digitizer arrangement for converting an analogue signal into a digital signal. It includes a first A/D converter that converts the analogue signal into a first digital signal with a lower sampling rate than the frequency of the analogue signal. Additionally, a second A/D converter converts a high-frequency analogue signal into a second digital signal, also with a lower sampling rate. The system combines both digital signals into a third digital signal with a sampling rate that is at least a multiple of the first and second sampling rates.
