Visualization of Chaff Cloud Aerodynamics based on Random Generation of Chaff Dipoles in 3D Space
Chaff is one of the most widely used and effective expendable electronic attack (EA) devices. It is a form of volumetric radar clutter consisting of multiple metalized radar reflectors known as chaff fibers designed to confuse hostile radar operation. It is dispensed into the atmosphere to deny radar acquisition, generate false targets. To understand the dynamics of chaff cloud, a software has ...
متن کاملFrom Backtracking to Chaff
Modern Chaff-like SAT solvers enhance plain backtracking (DLL) by Conflict-Driven Learning (CDL), including 1UIP-based Conflict-Directed Backjumping (CDB), Non-Chronological Backtracking (NCB), and 1UIP-based Conflict-Clause Recording (CCR). We show how to add these enhancements step-by-step to plain DLL to derive Chaff’s Conflict-Driven Learning algorithm, separately and independently of BCP, ...
متن کاملKeeping chaff minutiae in fingerprint templates
Fingerprint minutiae based biometric systems attract significant amount of attention as a secure user authentication method. In these systems, protecting the privacy of fingerprint templates plays a very important role in improving user’s acceptance upon providing their fingerprint information. However, due to the non-exact reproducible problem fingerprint minutiae templates can’t be protected ...
متن کاملSeparating Wheat from Chaff in Plant Genomes
0001 The recent discovery of a Hobbit-like hominid on the Indonesian island of Flores was startling in some respects—its rather modern existence, for one—but it represents a classic case of Darwinian evolution. For reasons that are not entirely clear, when animals make their way to isolated islands, they tend to evolve relatively quickly toward an outsized or pint-sized version of their mainlan...
