ANALYSIS OF CFAR DETECTION OF FLUCTUATING TARGETS [PDF]
Progress In Electromagnetics Research C, 2008 Our scope in this paper is to provide a complete analysis of CFARdetection of fluctuating targets when the radar receiver incoherently integrates M returned pulses from a chi-squared fluctuating targets with two and four degrees of freedom and operates in a multitarget environment.

Widespread Variation in Retinochrome Spectral Absorbance Across Scallop Phylogeny
Molecular Ecology, Volume 35, Issue 11, June 2026.ABSTRACT Vision is a two‐step process, including phototransduction initiated by a retinal‐bound opsin photopigment, and subsequent photopigment regeneration wherein the inactive state is restored. Because retinal isomerization, or changing of the molecular structural conformation, drives the activation of opsin photopigments, the reverse process is a ...

Target Tracking While Jamming by Airborne Radar for Low Probability of Detection
Sensors, 2018 Although radiation power minimization is the most important method for an advanced stealth aircraft to achieve the low probability of detection (LPD) performance against the opposite passive detection system (PDS), it is not always effective when the ...

Improving Of IS-CFAR Using Wavelet De-Noising For Smoothing The Noise In Reference Cells
Journal of Engineering and Sustainable Development, 2014 Constant false alarm rate (CFAR) algorithms allow RADAR systems to set detection thresholds and isolated the target from noise or clutter to keeping the false alarm rate at certain level.

An improved adaptive sidelobe blanker [PDF]
, 2008 We propose a two-stage detector consisting of a subspace detector followed by the whitened adaptive beamformer orthogonal rejection test. The performance analysis shows that it possesses the constant false alarm rate property with respect to the unknown
