Clutter Detection in Pulse-doppler Radar Systems

CLUTTER DETECTION IN PULSE-DOPPLER RADAR SYSTEMS Ahmet Güngör M.S. in Electrical and Electronics Engineering Supervisor: Assist. Prof. Dr. Sinan Gezici August 2010 Among various types of radar systems, the pulse-Doppler radar is the most widely used one, especially in military applications. Pulse Doppler radars have a primary objective to detect and estimate the range and the radial velocity of...

Output Feedback Tracking Sliding Mode Control with Parallel Feedforward Compensator

A new design method of output feedback type tracking sliding mode control (SMC) is proposed in this paper. Stability of the control system and the tracking performance to the reference input are achieved by using the parallel feedforward compensator (PFC), which guarantees almost strict positive realness (ASPR) of the plant, and the so-called internal model. Effectiveness of the method is shown...

Nonparametric clutter rejection in Doppler ultrasound using principal component analysis

We propose a new nonparametric technique for clutter rejection. We consider the Doppler data sampled using a sufficiently large dynamic range to allow for the clutter rejection to be implemented on the digital side. The Doppler signal is modeled as the summation of the true velocity signal, a clutter component, and a random noise component. To simplify the analysis, the first two components are...

Phase unwrapping for noisy phase map using localized compensator.

Phase unwrapping for a noisy image suffers from many singular points. Singularity-spreading methods are useful for the noisy image to regularize the singularity. However, the methods have a drawback of distorting phase distribution in a regular area that contains no singular points. When the singular points are confined in some local areas, the regular region is not distorted. This paper propos...
