Multiple-input, multipleoutput (MIMO) concepts were pioneered by the cell phone community to minimize the black spots caused by shadows in built-up areas. This technique uses differently located transmitters, each relaying the same message at the sam

Methods for improving the detection of concealed electronics, such as those used in improvised explosive devices (IEDs), are of continuing interest. In this regard, the harmonic radar, which utilises the non-linear junction (NLJ) effect, offers the p

Theory describing a super-resolution microscopy experiment using temporally and spatially coherent structured illumination was developed, and used to derive a method for processing experimental data. Numerical simulations were performed to verify tha

We describe the relationship between far field pattern synthesis for the co-array and the SAR array; showing the application of these to MIMO radar pattern synthesis. Whereas the original co-array concept was developed for planar arrays, the understa

This paper describes practical constraints on the use of MIMO radars imposed by the need for separable codes on each transmitter waveform, and where long code repetition intervals can degrade performance. This is especially problematic for long range

We introduce a new second-order method of texture analysis called Adaptive Multi-Scale Grey Level Co-occurrence Matrix (AMSGLCM), based on the well-known Grey Level Co-occurrence Matrix (GLCM) method. The method deviates significantly from GLCM in th

This paper describes a unified approach for evaluating ground-penetrating radar (GPR) maximum penetration depth and depth resolution performance independent of frequency. The method is based on the constant Q model, which approximately describes the

The growing professional interest in ground-penetrating radar (GPR) is driving the need to formulate methods for characterizing the performance capabilities of GPR systems. Because a number of different factors, such as antenna ringing, noise, radio

A small company in Brisbane working on MIMO radar systems was acquired by Teledyne Inc in Sept 2009. Continued support has allowed the development of several concept demonstrators where MIMO offers a distinct advantage. We describe two of these: a st

An algorithm for super resolution and sidelobe suppression is described for coherent collocated MIMO imaging radar. The algorithm modifies the coherent CLEAN method by performing a nonlinear least squares (NLLS) optimization in the beam domain. The N
