    • A volumetric phased array antenna system comprising a number of antenna elements, each of which is connected to a T/R (transmitter/receiver) module, being under the control of a beam steering computer (BSC), to which T/R module a transmitting signal is fed for forming a transmitting beam, via which T/R modules RF signals are received and via a radar receiver are fed to a signal processing unit connected thereto. The antenna elements are arranged in mutually spaced conformal curved virtual surfaces having the same center of curvature or the same centers of curvature, with each combination of antenna elements in one or more surfaces together forming a volumetric phased array antenna or a part thereof.

    • A monopulse phased array system comprises antenna elements with T/R modules controlled a beam steering computer. The space in which the antenna elements are arranged is divided into quadrants which are defined relative to the main axis of the radar beam. From the signals received by means of separate antenna elements, sum signals and first and second angle difference signals are derived: After combination of these signals delivered by the T/R modules, control signals are obtained for resteering the radar beam generated under the control of the computer mentioned. Each of the T/R modules is provided with two 180° phase shifters for determining the angle difference signals. After rotation of the radar beam, in the T/R modules of the antenna elements which are located in sectors whose sign of the axis direction perpendicular to the axis direction of the radar beam has changed through the rotation, a phase rotation of 180° is effected in the first angle difference signal and/or in the second angle difference signal.

    • A radar apparatus provided with a transmitting unit, antenna unit and a receiver unit. The transmitting unit transmits pulses having a modulation for enabling pulse compression on reception. As an ECCM feature, the radar apparatus is further provided with a blanking circuit. The blanking circuit includes two filters, one filter being responsive to the first half of the transmitting pulse only and the other filter being responsive to the second half of the transmitting pulse only. Blanking occurs if both filters simultaneously produce an output.
