Abstract: A radio-direction finding system (RDFS) comprises: at least one pair of substantially oppositely-positioned antenna arrays, each including directional antennas comprising at least one main antenna and one or more summation antennas; a plurality of individual radio- frequency (RF) receive paths, each of which are connected to a distinct main antenna only; and one or more common RF receive paths, each connected to a distinct pair of substantially oppositely-positioned summation antennas. The RDFS can analyze main output signals that are received from the individual RF receive paths to provide a coarse determination of a given direction from which a transmitting entity is transmitting radio signals, and provide a fine determination of the given direction utilizing one or more common output signals, received from one or more common RF receive paths, and a selected main output signal, the common output signals and the selected main output signal being associated with the coarse determination.

Abstract: System and for signal re-transmission including a channelizer, a signal-effect-processor and a controller. The signal-effect-processor includes a plurality of sub-band-processors and a summer. The channelizer receives a sampled Intermediate-Frequency signal exhibiting a first sampling-rate. The channelizer produces a plurality of sub-band-signals, each associated with a respective sub-band of the Intermediate-Frequency signal. Each sub-band-signal exhibit a second sampling-rate lower than the first sampling-rate. Each of at least one selected sub-band-processor receives a respective sub-band-signal, introduces at least one effect to the respective sub-band-signal, and increases the sampling-rate of the respective sub-band-signal to the first sampling-rate, thereby producing a respective affected sub-band re-transmit signal. Each selected sub-band-processor is further provides the respective affected sub-band re-transmit signal to a respective input of the summer. The summer sums the inputs thereof to produce a wideband affected re-transmit signal. The controller selects the selected sub-band processor and controls settings of the at least one effect.

Abstract: System for identifying the location of an emitter in an image. The system includes a receptor-array, an imager which includes an imaging-sensor, a multi-channel receiver which includes a correlator and a processor. The receptor-array includes at least three receptors. Each receptor receives the signal from the emitter and produces a respective received-signal. The imaging-sensor includes a plurality of pixels, each associated with a unique-identifier. The imager is at a fixed spatial relationship relative to the receptor-array. The field-of-view of the imager and the field-of-view of the receptor-array at least partially overlap. The correlator determines inter-receptor characteristic models. The processor determines a received-signals characteristic model from the inter-receptor characteristic models. The processor determines a pixel corresponding to the location of the emitter in the image according to a signal-to-pixel correspondence model optimizing an array-to-imager correspondence model. The array-to-imager correspondence model incorporates the received-signals characteristic model and the signal-to-pixel correspondence model.
