Abstract: An electronic bait station utilising the disruption of an electromagnetic field to detect the movement of insects or small animals within the station. The bait station consists of a housing, with at least one cavity having an electromagnetic radiation element generating an electromagnetic field in the cavity, and an electromagnetic receiving element detecting the electromagnetic field. Movement of an insect or small animal in the cavity causes a change in the electromagnetic field, which is detected. The preferred bait station comprises an outer cavity and a coaxial inner cavity, each with an electromagnetic field. This arrangement allows the direction of movement of insects and small animals to be determined and minimises the occurrence of spurious signals.

Abstract: Method and apparatus for extracting coherent information from in-phase (I) and quadrature (Q) signals. In a form, signals from an antenna array are mixed to form a plurality of I and Q signals that combined to form respective complex vectors. Each vector is adjusted in phase and magnitude to compensate for variations in field signal patterns, summed with other vectors, spatially and temporally filtered, and processed using spectral analysis algorithms to extract coherent spatial information. The coherent spatial information may be used to detect the presence, number and activity of insects within a structure in the near field of the antenna.

Abstract: A method and apparatus of detecting termites in which microwaves are transmitted into a region and reflected microwaves are detected. The received signals are processed to identify the presence or otherwise of termites or other insects. Various hardware configurations and signal processing algorithms are described including planar antenna arrays and neural net signal processing. The system comprises a microwave assembly, modulator and a processor. Microwaves are transmitted into a structure and the reflected microwaves are received in the microwave assembly. The output of the processor is displayed on a display.
