Space-Time Clutter Simulation and Characteristics Analysis for SBR

2009 International Joint Conference on Computational Sciences and Optimization, 2009
In order to develop clutter mitigation techniques, clutter simulation and characteristics analysis is very important. By introducing the clutter model of Space Based Radar (SBR) and discussing the earth's rotation effect to Doppler frequency, we get the space-time clutter spectrum of SBR.

Clutter Modeling and Characteristics Analysis for Bistatic SBR

IEEE National Radar Conference - Proceedings, 2007
In order to analyze clutter characteristics and develop clutter suppression method, clutter modeling is very important. In this paper, we introduce the clutter modeling method of bistatic space-based radar (SBR) and obtain the analytic resolution of the clutter isorange contour in a range gate. Besides, the Earth's rotation effect is taken into account

Analysis of Sea Clutter Characteristics at High Grazing Angle

2017 International Conference on Computer Systems, Electronics and Control (ICCSEC), 2017
The analysis of sea clutter statistical characteristics is very important for establishing a sea clutter model that can approximate the actual sea clutter as much as possible. In this paper, we systematically analyze the sea clutter characteristics including the time correlation, spatial correlation and Doppler characteristics of the measured data at ...

The Impact Analysis of Range Ambiguity for SABBR Clutter Doppler Characteristics

2018 IEEE International Conference on Signal Processing, Communications and Computing (ICSPCC), 2018
In the working process of space-air based bistatic radar (SABBR), the range ambiguity has a great influence on the clutter characteristics. In view of this issue, a clutter model is established based on the geometric relations and the calculation formulas of distance sum in this paper.

Range-ambiguous clutter characteristics in airborne FDA radar

Signal Processing, 2020
Abstract Frequency diverse array (FDA) has received much attention in recent years. Different from classic phased-array (PA) that uses the same carrier frequency for all array elements, FDA adopts a small frequency increment across its array elements to produce angle, range and even time dependent transmit beampattern, which provides many promising ...

Differential diagnostic characteristics between cluttering and stuttering—Part one

Journal of Fluency Disorders, 2009
Speech-language pathologists generally agree that cluttering and stuttering represent two different fluency disorders. Differential diagnostics between cluttering and stuttering is difficult because these disorders have similar characteristics and often occur in conjunction with each other. This paper presents an analysis of the differential diagnostic

Effects of geometry on clutter characteristics of bistatic radars

Proceedings of the 2003 IEEE Radar Conference (Cat. No. 03CH37474), 2004
This paper deals with the clutter characteristics of multichannel airborne radars. The analysis is performed using the clutter spectral center, which is a descriptive metric, in addition to commonly used measures such as Doppler-angle traces, iso-range, and iso-Doppler contours etc.
