摘要： Described herein is a method of preventing false detections in sensors pulse-Doppler radar mounted on a moving platform. The method comprises filtering each received burst using Doppler filtering to split each received burst into at least a fast channel and one or more slow channels. The slow channel outputs are then used to derive compensation values for the fast channel. In particular, a zero Doppler slow channel is used to derive predicted surface clutter residue information, and a near zero Doppler slow channel is used to derive additional false alarm control attenuation information. Both the predicted surface clutter residue and the false alarm control attenuation information is used to apply compensation to the fast channel and a comparison is done to select the lower of the two values to generate an output signal.

摘要： A method of classifying an object from which a pulsed Doppler radar signal is arranged to reflect according to the frequency spectrum of the reflected signal, is disclosed. The method comprises receiving the reflected signal at a receiver and processing the signal to generate a plurality of sub-signals which separately comprise a sub-spectrum of the frequency spectrum. The method further comprises determining the sub-signal having the largest amplitude and the amplitude of the sub-signal comprising the greatest frequency separation from the sub-signal having the largest amplitude. The method further comprises determining the difference between the amplitude of the sub-signal having the largest amplitude and amplitude of the sub-signal which comprises the greatest frequency separation from the sub-signal having the largest amplitude,and classifying the object according to the amplitude difference relative to a threshold.

摘要： There is disclosed a method for counteracting the effect which crags and other such environmental formations can have on radar returns or returns in similar sensor systems. In particular it has been found that the gaps between crags can lead to false detections because of firstly the function of certain signal processors which compare the high frequency return from a certain cell to a low frequency return from that cell, and secondly the effect of smearing of the returns from one cell to another. The invention seeks to mitigate this effect by selecting the maximum low frequency return from a group of range cells as the high frequency offset.

摘要： There is provided a sensor for use generally within the signal processing unit of a radar system. The sensor enables entity returns to be classified according to the velocity of the entity and thus allows returns to be processed according to classification. In particular the sensor comprises a first processing means that filters an input signal using a narrow-band notch filter to output a wideband output. In particular the sensor comprises a second processing means that filters an input signal using a wide-band notch filter to ouput a narrowband output. The invention provides for the comparison of the outputs to determine how the entity return is to be classified.
