This paper describes the design of silicon surface micromachined mirrors that were conceived for operation as part of an extremely large array of mirrors. Such an array has direct application to space-based imaging. For example, in certain spectromet

Ground Penetrating Radar (GPR) has been found to be a promising technology for detecting landmines. Landmines reflect electromagnetic energy in many directions, causing the GPR antenna to pick up these reflections at multiple positions with respect t

In this paper, a statistical technique for multi-sensor data fusion is applied to countermine problems. The fusion method has previously been shown to be a powerful tool in SAR/ATR applications. An earlier study, using data from the separate x, y and

The unattended sensing of stationary (i.e. non-mobile) targets is important in applications ranging from counter-proliferation to law enforcement. With stationary targets, sources of seismic, acoustic, and electro-magnetic emissions can potentially b
