摘要： This invention relates to a diode pumped slab laser in the form of a slab (1) where two opposite faces (2, 3) are adapted to receive pumping radiation with the faces being cut at the Brewsters angle at one end (6, 7) to provide entrance/exit faces for the lasing radiation. The laser radiation beam follows a zig-zag path in the slab (1) and is contained within the slab by total internal reflection. The laser slab (1) is contained within an optical cavity which results in the laser beam completing a double zig-zag beam path. The design results in good pump/mode matching, mitigates thermally induced birefringence problems, overcomes amplified spontaneous emission problems, requires no coatings or curved surfaces, and is easy and relatively inexpensive to make. The slab (1) can be used within both Quasi-CW and CW modes.

摘要： A pattern recognition system for using an artificial neural network architecture that is capable of using its memory to selectively attend to and recognise a learned pattern even when that pattern is embedded in a complex or noisy background. The proposed neural network is used for advanced signal processing in pattern recognition problems that are too difficult or not possible to be solved by the traditional approaches of artificial intelligence and engineering. The pattern recognition system has a neural network architecture consisting of at least two layers in communication with each other, the first layer being a memory layer and having means to store a plurality of memory fields, the second layer adapted to receive an external input and comprising a modulation means that modulates said external input to produce a modulated signal, a comparison means that compares the memory fields of the memory layer with the modulated signal and amplifies those portions of the modulated signal that are located in the memory fields thereby producing an indicator of a match between the memory field and the modulated signal.

摘要： A method of estimating missing data points at known positions in an input signal comprises the steps of: a) Fourier transforming the input signal from one of the frequency or time domains to the other; b) setting a threshold in the other domain so as to separate at least one unambiguous component of the transformed signal from the remaining components including noise; c) inverse Fourier transforming the separated component back to the original domain; d) replacing the missing data points at the known positions in the input signal with data comprising the values of the inverse Fourier transformed separated components at the known positions to generate an improved signal. The steps (a) to (d) are iterated to achieve a desired level of input signal improvement.

摘要： The transmitter (1) transmits signals in the form of symbols to a receiver (2). The received signals are analyzed and a probability density function estimate is formed in a pdf estimating means (4). There is a memory means (5) which contains a library of known probability density functions. A comparison means (6) compares the measured histogram from the pdf estimating means (4) with those stored in the memory means (5). The comparison means (6) produces an index (8) which uniquely identifies the library pdf most closely matching the measured pdf. The index (8) is fed back. At the transmitting end of the communication link the index (8) is used to select the corresponding pdf from memory means (7). Memory means (7) and memory means (5) are equivalent. The pdf extracted from memory means (7) is used to adjust the transmission parameters of the system.

摘要： An apparatus (10) for generating one or more radar return signals representative of one or more remote objects useable in ground based, shipboard and airborne radar systems (16) for testing the radar and its user. The apparatus may generate one or more return signal scenarios which may if required interact with the real or preprogrammed movement of the craft in which the radar (16) is fitted. To ensure accurate and repeatable radar return signal generator apparatus (10) operation, the radar's own built-in test signal (21) output is used by the apparatus to calibrate the radio frequency portion of the apparatus which adapts a remote object return signal scenario into the crafts radar device (16). To further improve the accuracy of the return signal a digital first-in-first-out (FIFO 32) delay means is used to accurately allow the delayed reuse of the radar's own transmission signal.

摘要： A radar receiving system which includes an array of receiving antennas for receiving radar signals over a frequency range, fmin to fmax, the antennas of the array being separated by a distance proportional to c/fmax. A control system directs alternate ones of the antennas, for example every second one, to receive radar signals direct from a radar transmitting system for lower frequencies in the frequency range, and directs the remaining antennas to receive radar signals returned from a target area of the transmitting system. If desired, selected ones of the antennas can be directed to receive radar signals direct from the radar transmitting system for higher frequencies in the frequency range, the remaining antennas being directed to receive the radar signals returned from the target area.
