A Robust Recursive Filter for RadarPulse Train Parameter Estimation andTrackingStephen
نویسندگان
چکیده
A robust lter for the estimation of the pulse repetition interval (PRI) of a periodic radar pulse train is derived. The lter uses only the pulse times of arrival (TOA) and is speciically designed, using mixture distribution techniques developed for the robustiication of the Kalman lter to outliers, to be robust to both missing pulses and to a small number of spurious noise pulses. In fact, the lter actually uses the multiple PRI time intervals due to missing pulses to improve the PRI estimate. The performance of the lter is demonstrated using both simulated data and TOA measurements from an operational radar.

An Adaptive Robustifying Approach to Fir Filtering
In this paper, a new robust adaptive FIR filter algorithm with variable forgetting factor for time-varying parameters estimation in the presence of impulsive noise is discussed. The proposed algorithm is based on the robust recursive least square and parallel adaptation recursive least square algorithms combination. A scalar parameter controls the switching process between these two algorithms,...

Estimating the volume of groundwater contribution to runoff within a watershed is one of the most important subjects in water resources management and hydrology. In this paper, groundwater contribution to total runoff as a base flow index was estimated using hydrograph separation in six stream gauging stations in southwest of Iran. The major objective of this research is to distinguish the most...

متن کاملRecursive Structure from Motion Using Hybrid Matching Constraints with Error Feedback
We propose an algorithm for recursive estimation of structure and motion in rigid body perspective dynamic systems, based on the novel concept of continuous-differential matching constraints for the estimation of the velocity parameters. The parameter estimation procedure is fused with a continuous-discrete extended Kalman filter for the state estimation. Also, the structure and motion estimati...
