This paper proposes a new method for improving Signal-to-Clutter Ratio (SCR) for millimeter wave Frequency-Modulated-Continuous-Wave (FM-CW) radar. Received echoes of FM-CW radar can be categorized into two types due to either a target or clutter. Generally, the target received data have a stronger correlation with respect to different carrier frequencies than that of the clutter received data....

In this paper, we consider the signal model and parameter estimation for multiple-input multiple-output (MIMO) radar with colocated antennas on stationary platforms. Considering internal clutter motion, a closed form of the covariance matrix of the clutter signal is derived. Based on the proposed closed form and low rank property of the clutter covariance matrix and by using the singular value ...

Vegetation clutter is a limiting factor for bats that forage near ground level, and may determine the distribution of species and guilds. However, many studies that evaluated the effects of vegetation clutter on bats have used qualitative descriptions rather than direct measurements of vegetation density. Moreover, few studies have evaluated the effect of vegetation clutter on a regional scale....

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...

APPROVED FOR PUBLIC RELEASE Land clutter issues and modelling from a perspective of L-band VV polarisation are addressed. In particular, clutter distributions in three different dimensions are discussed in detail. First a three-term model for the dependence of land clutter on grazing angle is proposed. The model is site-specific and landcover-dependent. Parameters for dominant types of landcove...

This paper addresses the effect of clutter in direction of arrival (DOA) tracking from a passive acoustic sensor station. DOA signal is characterized by non-linearities arising from the measurement model. Strong dynamics combined with signal deterioration such as clutter can cause filters to diverge. A family of Monte Carlo methods known as particle filters has been used in variety of problems ...

The effectiveness of information visualization largely depends on the ease and accuracy with which users can access the information. Visual clutter in a display can detract from a user’s ability to properly read the information. An ideal visualization needs to maximize the visibility of patterns and structure and minimize the clutter present. Thus far, there has been surprisingly little work do...
