Abstract: The invention concerns a system (100) and a method for estimating the geographic position of a target (1). The method comprises the following steps: detecting a target (1); determining the characteristics of the target (1), which characteristics at least comprise a geographic position (3) and a category of the target; tracking the detected target (1) until at least one certain predetermined criteria is not fulfilled, wherein said criteria is associated to the level of certainty for determining the geographic position (3) of the target (1). The method further comprises determining a first point in time t1 when the predetermined criteria was last fulfilled, wherein, for a second point in time t2 the following step is performed: creating a pattern (2) defining at least one possible geographic position (3) of the target (1), said pattern (2) extends at least partially around the geographic position (3) of the target (1) at t1, wherein the dimension of said pattern (2) is determined based on at least one predetermined parameter.

Abstract: Provided is a dual-band multimode antenna feed for a high-frequency band and a low-frequency band. The feed includes four high-frequency waveguide ports, where each high-frequency waveguide port is connected to a respective high-frequency input/output waveguide. Each high-frequency input/output waveguide includes a high-frequency waveguide aperture facing a first section for mixing electromagnetic modes in the E-plane. The first section is connected to a second section for mixing electromagnetic modes in the H-plane. The feed further includes a low-frequency waveguide port connected to a low-frequency input/output waveguide. A filter is arranged inside the first section to be transparent for plane wave modes exhibited at lower frequencies and reflecting for plane wave modes exhibited at higher frequencies.

Abstract: A method for operating a radar in a radar system to cancel an external disturbance in a received signal is provided. The method comprises receiving a signal at the receiving antenna, receiving the signal at the control unit, identifying interfering signal, generating a correction signal and feeding the correction signal. The correction signal is arranged to dampen the interfering signal in the frequency span in the received signal. Thereby the external disturbance is reduced.

Abstract: The present invention relates to a substantially spheroidal fragmentation device (10). The fragmentation device (10) comprises: i) a protective exterior layer (6) of resilient material accommodating at least one warhead (9); ii) an inner core (11) protected by said exterior layer (6). The inner core (11) comprises: ii.a) an insensitive munition (IM); ii.b) a polymeric, plastic and/or rubbery matrix embedding the insensitive munition (IM); ii.c) explosive material (5) enclosed within the matrix of ii.b) and/or surrounding the matrix of ii.b). The ratio of the thickness of the protective exterior layer (6) to the radius of the fragmentation device (10) ranges from 0.1:1 to 0.7:1. The warhead (9) is accommodated within the protective exterior layer (6) or between the inner core (11) and the protective exterior layer (6). The invention also relates to a method of firing a fragmentation device (10) as disclosed herein, wherein a firearm is aimed at a surface enabling rebounding of the fragmentation device (10) whereby the fragmentation device (10) changes direction. The invention also relates to the use of a fragmentation device (10) as disclosed herein in a firearm.
