On the basis of the extended Kalman Filter(EKF) and the decaying extended Kalman Filter,this paper makes use of the modified strong tracking filter(STF) to estimate the maneuvering target information without all measurement information.

A new tracking filter was proposed for the highly non-linear single observer passive location and tracking(SOPLAT)system,where the common tracking filters often failed to catch and kept tracking of the emitter.

But to the CW pulse signal with changing frequency, it is difficulte to realize tracking filter with common narrowband filter.

Image segmentation methods applied for Airborne Pulse doppler clutter tracking;

This paper introduces a clutter tracking technique used for airborne PD radar.

Based on clutter tracking,we proposed CF(clutter feature) CFAR detector and SE(structuring element) CFAR detector,analyzed and simulated their detection performance by the Monte Carlo method.

Design and realization of carrier tracking for GNSS receiver

Technology of carrier tracking for high dynamic signals based on FLL and PLL cascade

This paper introduces the principles of code acquisition and carrier tracking for high dynamic GPS receivers,and gives a technical method to realize the digital dynamic carrier tracking with the PLL+FLL based on DSP.
