    Diagonal loading is one of the most widely used and effective methods to improve robustness of adaptive beamformers. The authors consider its application to the case of steering vector errors, i.e. when there exists a mismatch between the actual steering vector of interest and the presumed one. More precisely, the problem addressed is that of optimally selecting the loading level with a view to ma... View full abstract»

    The Kalman filter (KF) has been widely used in the state estimation of a target, but in the presence of a manoeuvre, its performance may be seriously degraded because the manoeuvre appears as extensive noise on the target model and the process noise variance cannot cover it. To solve this problem, a new intelligent KF (IKF) is proposed for tracking a manoeuvring target. The unknown target accelera... View full abstract»

    The paper deals with a radar 'track before detect' application in a multitarget setting. 'Track before detect' is a method to track weak objects on the basis of raw radar measurements, e.g. the reflected power of the target plus noise. In classical target tracking, the tracking process is performed on the basis of pre-processed measurements that are constructed from the original measurement data e... View full abstract»

    Based on the linear prediction property of sinusoidal signals, a new adaptive method is proposed for frequency estimation of a real tone in white noise. Using the least mean square approach, the estimator is computationally efficient and it provides unbiased and direct frequency measurements on a sample-by-sample basis. Convergence behaviour of the estimated frequency is analysed and its variance ... View full abstract»

    A new and unique millimetre wave radar capability is described. A coherent quasi-monostatic 77 GHz polarimetric short range phase coded pulse Doppler (PCPD) radar is integrated with a coherent monostatic 77 GHz co-polar continuous wave (CW) fast event radar data capture facility to provide unparalleled functionality in a single unit. The PCPD radar, originally designed for the short range radar me... View full abstract»

    Radar sensors are widely used in automotive on-board systems such as adaptive cruise control, which tracks the preceding vehicle and keeps a safe distance. The authors go a step further and exploit the potential of a high resolution radar sensor for the estimation of the road borders and the reconstruction of the traffic scenario based on object tracking. A FMCW millimetre wave radar is mounted in... View full abstract»

    Consistent and realistic error covariance information is important for position estimation, error analysis, fault detection, and integer ambiguity resolution for the applications of global navigation satellite systems. In designing a position domain carrier-smoothed-code filter where incremental carrier-phases are used for time-propagation, formulation of consistent error covariance information is...
