A system for determination of a direction to an object emitting and/or reflecting electromagnetic radiation, comprising: a first pair of linearly polarized antennas having a first type of polarization and separated by a first predetermined distance defining a first baseline, said first pair of linearly polarized antennas configured for receiving a polarized signal of the first type of polarization originated from the object; a second pair of linearly polarized antennas having a second type of polarization orthogonal to the polarization of the first pair and separated by a second predetermined distance defining a second baseline, said second pair of linearly polarized antennas configured for receiving another polarized signal of the second type of polarization originated from the object, the first baseline and the second baseline intersecting at right angles to define four quadrant parts; four receivers coupled to the linearly polarized antennas of the first and second pairs, wherein each receiver associated with at least one pair of the antennas includes a phase shifter configured to receive polarized signals, to provide a required phase shift to the received polarized signals, and to generate corresponding phase-shifted polarized signals; and a signal processing system coupled to said four receivers, and configured (a) to combine the phase-shifted polarized signals originated from said at least one pair of the antennas with non-shifted signals originated from another pair of the antennas, thereby forming four virtual antennas having a desired polarization with phase centers located in said four quadrant parts, correspondingly; and (b) to process the signals having the desired polarization associated with said four virtual antennas for generating at least one direction parameter of the object. a first pair of linearly polarized antennas having a first type of polarization and separated by a first predetermined distance defining a first baseline, said first pair of linearly polarized antennas configured for receiving a polarized signal of the first type of polarization originated from the object; a second pair of linearly polarized antennas having a second type of polarization orthogonal to the polarization of the first pair and separated by a second predetermined distance defining a second baseline, said second pair of linearly polarized antennas configured for receiving another polarized signal of the second type of polarization originated from the object, the first baseline and the second baseline intersecting at right angles to define four quadrant parts; four receivers coupled to the linearly polarized antennas of the first and second pairs, wherein each receiver associated with at least one pair of the antennas includes a phase shifter configured to receive polarized signals, to provide a required phase shift to the received polarized signals, and to generate corresponding phase-shifted polarized signals; and a signal processing system coupled to said four receivers, and configured (a) to combine the phase-shifted polarized signals originated from said at least one pair of the antennas with non-shifted signals originated from another pair of the antennas, thereby forming four virtual antennas having a desired polarization with phase centers located in said four quadrant parts, correspondingly; and (b) to process the signals having the desired polarization associated with said four virtual antennas for generating at least one direction parameter of the object. <EOS>
