Next are descriptions of antenna performance metrics used to evaluate performance: peak gain, maximum sidelobe level, beamwidths, and integrated sidelobe level (ISL). Then it is shown that plane waves are solutions of Max

Greg Friedman,Cynthia Greenfield itself; (2) signals add coherently whereas noise adds incoherently; (3) signal-to-noise ratio (SNR) gain at the receiver is only accomplished by voltage integration; (4) radio performance goes as one over the square-root of the SNR. The keys to understanding the SNR in a receiver are Friis’ Link Ma

Karen Levy,Gretchen Daily,Samuel S. Myersquation is particularly mysterious when one considers the origin of the coefficients 0.876 and 36.K. In this chapter, the basic principles behind this expression are discussed, and it is shown to be valid for a 1950s type of antenna with high back or sidelobes. A general expression that applies to m
