Abstract (en)
[origin: EP0709914A1] The search heads are part of an hf antenna system disposed on an e.g. dielectric carrier plate. The antenna system is composed of a group of four logarithmic-periodic cross-dipole antennas. The dipole axes are inclined towards each other in the radiating direction. Sum and difference diagrams are obtained using a monopole supply network in azimuth and elevation. The phase centres of the active cross-dipoles are separated by a maximum of 0.7<*>lambda. The system may also include optronic or millimetre wave sensors.
