  • Patent number: 9270020
    Abstract: The invention provides an antenna arrangement for a radar system arranged for coverage of a surveillance area and comprising antenna elements. The antenna elements are arranged to receive a signal transmitted from a transmit antenna of a transmit antenna arrangement and reflected by a target towards the antenna arrangement wherein: • the antenna arrangement comprises at least two non-parallel line arrays, • each antenna element being connected to a receiver where each line array is arranged to create, by using digital beam forming, beams for instantaneous coverage of at least said surveillance area and • within the surveillance area said line arrays are arranged to allow the target position to be limited to one or two crossing areas between at least two beams from different line arrays from which target reflections have been received. The invention also provides a corresponding method and a radar system comprising the antenna arrangement.

  • Patent number: 9192047
    Abstract: A mounting system adapted to receive a plurality of transmitter receiver modules and each including an upper antenna part and a lower electronic components part. The lower part includes transmitter receiver module contacts on the end opposite the upper part. The mounting system includes a substrate rear panel including transmitter receiver module contact receivers on a first side and active support units on a second side. Each contact receiver is adapted to receive transmitter receiver module contacts of one receiver module. The supports are adapted to support a plurality of receiver modules. One single substrate rear panel is adapted to receive the receiver modules in a matrix. The mounting system includes a ground plane and an electric conductive sheet, and is arranged such that when the receiver modules are mounted in the mounting system, the ground plane levels with the receiver modules transition from the upper to the lower part.
