Abstract
A system and method for determination of a direction to an object emitting and/or reflecting electromagnetic radiation. The system includes a first pair of linearly polarized antennas configured for receiving a polarized signal of a first polarization type and a second pair of linearly polarized antennas configured for receiving another polarized signal of the polarization second type originated from the object. The system includes four receivers coupled to the linearly polarized antennas of the first and second pairs and a signal processing system coupled to the receivers. Each receiver associated with at least one pair of the antennas, includes a phase shifter to provide a required phase shift to the received polarized signals. The signal processing system combines the phase-shifted polarized signals with non-shifted signals which are originated from different pairs of the antennas, and to process these signals for generating at least one direction parameter of the object.
