Infrared surveillance system for surface-to-air defense

Abstract: A land-based, passive IR system for the detection of airborne targets has been developed at Saab Missiles. The system operates in the 8 - 12 micrometers region. It scans 360 degree(s) in azimuth and up to 45 degree(s) in elevation and detects targets automatically. The paper describes the system in general, and in more detail the principles of the signal processing, that enable automatic detection of targets in the thermal clutter of sky and terrain background. A unique concept for rejection of false alarms from small objects at short distance (birds) is also described.

ICNS Conference 2013: Airport surface movement in the NextGen ERA

Abstract: NextGen is an evolutionary process, but there are many aspects that are already here and are providing real surface efficiency benefits.

Adaptive Kernel background intensity estimation based on local 2D orientation

Abstract: Many target tracking algorithms for radar systems assume homogeneous backgrounds of clutter. However, real backgrounds are rarely homogeneous. By estimating background intensity, and using the estimate in the likelihood measure, the tracking algorithm is given the ability to adapt to the background. In this work, a method for estimating the clutter intensity is introduced. The method is based on locally adaptive Kernel Density Estimation (KDE), where local 2D structure of the background in terms of energy and orientation controls the smoothing properties of the filter kernels. In regions with low clutter intensity, the kernel adopts low-pass characteristics, and the intensity estimate is based on observations from a larger volume. In regions where there are ridges in the clutter intensity, kernels are selected such that smoothing is carried out along ridges instead of across them. Peaks in the clutter intensity are left unsmoothed. The proposed method is compared to other methods on synthetic data. Additionally, a demonstration is given on recorded radar data.

An Experimental Study on the Strength of Out of Plane Loaded Composite Structures

Abstract: More and more composite materials are used within primary load carrying aircraft structures. Examples are Boeing 787 and Airbus A350XWB where the composite content has increased up to 50–60 % by weight. With the aim to decrease manufacturing cost the structures are given a higher degree of integration and complexity. More integrated structures give fewer articles and fewer steps in the manufacturing chain. In many cases new innovative design solutions are a requirement to enable integrated structures.
