Find the half-power beamwidth (HPBW) and first-null beamwidth (FNBW), in radians, for the following normalized radiation intensity U(?)=cos(4?) where (0? ? ? ?/2, 0??? 2?). HPBW= _____ radians and FNBW= _____ radians
You are an antenna engineer and you are asked to design a high directivity/gain antenna for a space-borne communication system operating at 10 GHz. The specifications of the antenna are such that its pattern consists basically of one major lobe and, for simplicity, no minor lobes (if there are any minor lobes they are of such very low intensity and you can assume they are negligible/zero). Also it is desired that the pattern is symmetrical in the azimuthal plane. In...
Question 1 The power radiated by a lossless antenna is 10 watts. The directional characteristics of the antenna are represented by the radiation intensity of U = 2cos3θ watts/unit solid angle. Find the (a) Maximum power density at a distance of 1000 m (assume far-field distance) (b) Maximum directivity (c) Maximum gain Question 2 In target-search ground-mapping radars it is desirable to have echo power received from a target, of constant cross section, to be independent ofits range. For one such application, the desirable radiation intensity...

AHS 375-Homework 11 Due: 2 October 2019 30 Sep 2019 1. Show that pressure decreases more rapidly with height in a cold layer of air than in a warm layer. Hint: start with hydrostatic balance and make use of the ideal gas law. 2. Use the hypsometric equation to determine how much the mean virtual temperature of the 1000 hPa to 850 hPa layer would change if the thickness of the layer decreased by 20 m. Would the mean virtual...
