    摘要: A ground penetrating radar includes a signal generator, a return signal processor, a gate and an antenna. The signal generator is a dual frequency synthesizer that generates a stepped frequency master signal and a tracking signal offset by an intermediate frequency. The return signal processor is a dual channel quadrature receiver that mixes down a return signal and a sample of the master signal to intermediate frequency using the tracking signal. The signal generator is pulsed by the gate and the return signal is gated at the same frequency. Hollow pyramidal antennas are also described that have an ultrawide band bowtie structure with antenna electronics located within one antenna element. A method of operating the radar is also described.

    摘要: A slope monitoring system having a radar and a video camera recording images sequences of the slope. A data processing unit performs coordinate registration to align the radar images and the video images. Interferometry is used to detect movement in the slope by generating interference maps between the images. These are suitably phase maps showing the phase change between a radar image and a reference image. An alarm occurs if a significant movement is detected.

    摘要: Systems and methods of error handling in interferometric signal processing for a ground based slope monitoring system are described. Uncorrected movement data is extracted from interferometric radar measurements of a relatively stable reference. The movement data is corrected for changes in atmospheric conditions as a function of changes in a refractive index of the air and an offset induced at zero range.

    摘要: A method of error handling in a slope monitoring system that generates slope movement data from interferometric signal processing of radar images of the slope monitoring system. The error handling occurs in two steps. The movement data is corrected for changes in atmospheric conditions and disturbances are identified. It is convenient to mask the regions identified as disturbed in the display of the corrected movement data. Typical disturbances include short term disturbances, such as trucks, and long term disturbances, such as vegetation.

    摘要: A perimeter antenna array for a radar, in particular a slope monitoring radar, formed from a pair of parallel linear arrays of receiver elements and a pair of parallel linear arrays of receiver elements, together forming a rectangle of receiver and transmitter elements. Signals are switched to the transmitter elements and received by the receiving elements. The signals are processed to obtain signals for virtual elements located equidistant between transmitting and receiving elements. The signals from the virtual elements are analyzed to produce a radar image.
