LOW POWER INJECTION FOR DIRECTION FINDING WITH SIX-PORT REFLECTOMETER ARRAY

摘要

In this paper, we propose a new method to estimate the phase of the reflection coefficient (PRC), created at the outputs of a six-port reflectometer (SPR), with respect to its input signal phase (RF). This method is essential to determine the direction of arrival (DOA) of the RF signal without baseband and without demodulation system. We present the study of PRC finding with low power injection at the RF input and at the Local Oscillator input (LO) at 2.45 GHz. The new method is deduced from the simulation of the characteristics of a SPR system, with polarized diode detectors, using the Advanced Design System (ADS).
