Method for conversion of waveguide modes, mode-converting arrangement and antenna arrangement.

Abstract: The invention relates to a method for conversion of waveguide modes from a mode of type TM01 to mode of type TE11 for transmission of power within the microwave range. The invention also relates to a mode-converting arrangement and an antenna arrangement with such a mode-converting arrangement. The mode-converting arrangement comprises an incoming waveguide (1) for reception of power of the type TM01, an outgoing waveguide (6) for outputting power of mode type TE11 and a waveguide-mode-converting section (2-5) arranged between the incoming and outgoing waveguides. According to the invention, incoming power of mode type TM01 is divided in an input section (2) between two or more waveguides with cross-sections in the shape of circle sectors. Thereafter, the divided power is phase-shifted by the waveguides in a subsequent phase-shift section (4) being designed with cross-sections that are essentially in the shape of circle sectors with different radii, after which the waveguides are changed into a common essentially circular waveguide (6) that emits an otugoing power of mode type TE11. By means of the invention, a relatively simple solution is produced, that can cope with high powers.

Distributed power amplifier with active matching

Abstract: A distributed power amplifier arranged to operate over a bandwidth. An input side with an input terminal is arranged to receive an input signal and connected to an input transmission line. An output side with an output terminal is adapted to deliver an output signal and connected to an output transmission line. A power splitter is connected to the input terminal, thus being arranged to divide the input signal in a first path to the input transmission line and in a second path to an input of an active matching circuit. The active matching circuit has an output connected to the output transmission line. The other end of the output transmission line is connected to the output terminal. A method to design a distributed power amplifier and to modify existing distributed power amplifiers.

A method for resource allocation in mission planning

Abstract: The present invention relates to a method for planning attacking to optimize the use of own available resources and effecting attacking of targets in a target area (15) based upon information on own resources available for attacking and information on protected and non-protected targets located in the target area. The method comprises collecting different attack tactics in a first library (5) and collecting strategies to defend a target area to be attacked in a second library (6), allotting each target (16, 17, 18) in the target area (15) a reward value, evaluating different attack tactics for a chosen defend tactic to find an optimal attack tactic having highest possible collected reward value, the found optimal attack tactic being used to create an attack plan involving information on inter alia resources needed, targets to attack and attacking directions The object of the invention is to obtain a more effective use of available resources.

IM-lock for weapons having preloaded projectiles

Abstract: A weapon having a barrel or launch tube and a projectile preloaded therein. An element prevents accidental firing of the projectile if the weapon becomes overheated.

09E-SIW-014 core technical framework study: a service framework for distributed simulations in net-centric environments

Abstract: The goal of the Core Technical Framework study is to define a framework that promotes secure, multinational distributed simulation. The main domains targeted are Training, Simulation Based Acquisition (SBA), Concept Development and Experimentation (CD&E). The framework benefits from, and can be easily integrated with, Enterprise Architecture Frameworks descriptions compliant to NAF and MODAF. This paper will describe a Service Framework for Distributed Simulations in a net centric environment, enabling a closer integration of heterogeneous simulation architectures, simulation assets and support for automation of Exercise management. By using a service paradigm for distributed simulations, assets and functionalities may be packaged and reused. As an example, a federate may be reused and shared by different federations and different stakeholders.
