A novel concept of a homodyne microwave sensor performance: Progress report

The mathematical description of the systems consisting of a quadrature microwave sensor (MS) of homodyne configuration, antenna and target is performed based on the well-known energy relation between the signal power and the distance under free-space conditions. The original approach to the homodyne MS operation was developed for the case of RF oscillator frequency, f variations with discrete steps, Deltaf_n. A number of important advantages of the proposed MS concept are described.
