    The paper presents a 3-D near-field source localisation algorithm using a bottom mounted linear sensor array for a multipath environment. The proposed algorithm utilises the signals from different paths plus a simple linear sensor array to estimate the 3-D location of a source, whereas conventional 3-D localisation algorithms require a 2-D array of sensors. The conic angles of the source signal ar... View full abstract»

    The applications using differential GPS (DGPS) have grown over the years, and the dominant error source for many DGPS techniques is reference receiver multipath. As a result, there is great interest in reducing reference receiver multipath, especially for safety-critical applications such as DGPS-based precision landing. A new method for reducing code and carrier phase multipath is presented which... View full abstract»

    Ultra-wideband (UWB) monostatic ground-penetrating radar (GPR) has been proven to be very useful in road and highway pavement profiling. Pavement profiling involves estimating the thickness and permittivity of each underground layer, which can be done through layer stripping inversion, using efficient time-delay-estimation algorithms. In monostatic GPR applications, time delay estimation is routin... View full abstract»

  • PFA algorithm for airborne spotlight SAR imaging with nonideal motions

    Publication Year: 2002, Page(s):174 - 182

    The nonuniform-interpolation polar format algorithm is developed for processing spotlight SAR data with nonideal platform motions. Instead of two uniform interpolations for the conventional polar format algorithm (PFA), this algorithm employs a one-dimensional uniform interpolation in the range direction and a one-dimensional nonuniform interpolation in the azimuth direction to remove effects of n...

    For the problem of estimating the time-difference-of-arrival (TDOA) of radio waves impinging on one or a pair of antennas for the purpose of actively or passively locating the source of a communications or telemetry signal in the presence of interfering signals and noise, W A. Gardner has developed some effective methods, such as CCCC and SPECCOA etc. However, it is shown that CCCC, SPECCOA and re... View full abstract»

  • Spotlight MUSIC: super-resolution with subarrays with low calibration effort

    Publication Year: 2002, Page(s):166 - 173

    A central problem in applying super-resolution to phased arrays is the knowledge of the 'array manifold', i.e. the complete knowledge of the array outputs for a plane wave impinging on the array from all considered directions. This becomes a problem for large arrays where only subarray outputs are digitised. In the paper methods for determining an array manifold model with minimum knowledge of the... View full abstract»
