Under the genomic radar: the stealth model of Alu amplification.
Alu elements are the most successful SINEs (Short INterspersed Elements) in primate genomes and have reached more than 1,000,000 copies in the human genome. The amplification of most Alu elements is thought to occur through a limited number of hyperactive "master" genes that produce a high number of copies during long evolutionary periods of time. However, the existence of long-lived, low-activ...
متن کاملRadar Signal Detection in K-distributed Clutter by Pade Approximation
In this paper, two suboptimum detectors are proposed for coherent radar signal detection in K-distributed clutter. Assuming certain values for several initial moments of clutter amplitude, the characteristic function of the clutter amplitude is approximated by a limited series. Using the Pade approximation, it is then converted to a rational fraction. Thus, the pdf of the clutter amplitude is o...
متن کاملModified matched signal transform for parameter estimation of spread spectrum stretch signal
The spread spectrum stretch (S-cubed) is a kind of hybrid signal which has the advantages of the expansion and wide instantaneous bandwidth, proved to be the potential option for low probability of intercept (LPI) radar and stealth communications. In this paper, the S-cubed model that superimposes a short, cyclically repeated, discrete phase code on linear frequency modulation (LFM) is presente...
متن کاملNyquist Folding Receiver for the Interception of Frequency Agile Radar Signal
This work was carried out to improve the probability of interception of frequency sweep and lower the system complexity of non-sweep mode of the electronic intelligence system for frequency agile radar signal. A low complexity receiver structure and its associated demodulation algorithm with high probability of intercept are also presented. Moreover, the applicability of this structure for the ...
