Title: Innovations of Norman F Powell

Introduction

Norman F Powell is a notable inventor based in Ilchester, MD (US). He has made significant contributions to the field of radar technology, holding a total of 5 patents. His work has advanced the capabilities of radar systems, making them more efficient and effective.

Latest Patents

Among his latest patents is a "Radar system and method having variable tracking range." This invention features a segmented stretch waveform designed for wide band high duty cycle tracking applications. The waveform is divided into multiples of two spaced segments as the tracking range closes. Target returns received during these spaced segments are combined to correspond to the complete waveform, allowing for range determination based on the combined waveform. This system enables the tracking range to be varied without altering bandwidth, FM slope, duty cycle, or processing time.

Another significant patent is the "System for obscuring antenna sidelobe signals." This invention comprises a jam-resistant radar system that includes a primary radar transmitter coupled to a primary antenna with a predominant main beam and sidelobes. A second wide beam antenna is linked to a second radar transmitter, which transmits a signal with a frequency spectrum that encompasses the main beam. The power density of this signal is substantially equal to that of the sidelobes of the primary antenna. The second transmitter is frequency modulated over a spectrum in discrete steps, while the primary transmitter is randomly modulated over the spectrum. This design prevents a listening jammer positioned in the sidelobes from determining the frequency used by the primary radar transmitter.
