602 EXAMPLES OF RADAR SYSTEM DESIGN [SEC. 15.8 Further decrease of bearnwidth below 1° should be advantageous operational}+, although improvements due to increased resolution may not be as marked in this region as they were in the region above 1°. If wavelength is decreased below the 10-cm region to sharpen the beam, coverage requirements will become more difficult to meet, even with the assumption that component performance is independent of wavelength. Because of coverage demands and for other reasons to be discussed later, a decrease of wavelength belo\\-abo~~t 8 cm to sharpen the beamwidth does not appear desirable. .\n increase of antenna width beyond 25 ft to sharpen the beam would hare the ad\-antage of improving co~-erage, but the following limitations would be encountered: 1. If the set is to l)e mobile or easily tran~portablej an antenna of greater wi(ith is cumbersome. N-ith proper construction, an antenna perhaps 35 ft wide might be satisfactory. 2. The requirement (for good gain per unit area) that the reflector shape shall not clepart from the shape desired by more than about, O.1X becomes increasingly difficult to meet as antenna width is increasrd lm~-onti 25 ft. >-0 difficulty ~vas exp~rienced in maintaining this tolcranrc ~~-itha 25-ft reflector, but the tolerance problem Ivas foun(l to be sf’~-erefor an experimental 50-ft reflector con- ~tr[lctcd for a particular application.

SEC. 15.8] CHOICE OF BEAM SHAPE 603 provided by addition of a third system, but the additional complexity was thought to be operationally not worth its cost. Reflection of radiation from the earth’s surface greatly influences the radar beam characteristics in elevation angle, and such effects must be given careful consideration. Over water, the reflection coefficient is high for all wavelengths of interest for air surveillance, and for very small angles of incidence it can be assumed to be 100 per cent. Over land, the reflection coefficient varies markedly with detailed surface shape and with the composition of the terrain, and in general increases with increasing wavelength. Adequate data are not available on the reflection coefficient, but at wavelengths of 10 cm or less it is assumed to be normally negligible, and at a few meters it is normally substantial. ~ ẓ 2 :: 5 c .- 1 s 2 g g < 0 Rance in miles FIG. 15.5.—Calibrated vertical-coverage diagram of actual radar using 7-in. B-scope with antenna rotating at 2 rpm. Effective antenna height is 100 ft. Target is a single B-24. The detailed effects of surface reflection which influence coverage are very complex. Some of the more important effects and conclusions are summarized below (see also Sec. 2.12). 1. 2. 3. 4. If surface reflection is high, the lowest possible angle of coverage is raised from the horizon to an angle a = k/2h, where a is in radians and h is the height of the antenna above the surface. If surface reflection is low, radiation striking the surface is lost. It is clearly desirable to minimize this loss by beam-shaping. Over an angular region in elevation where reflected intensity equals direct intensity, R~,, at the center of an interference lobe is doubled, but midway between two lobes R~.X = O. At long wavelengths (one meter or greater), the use of reflected radiation reduces requirements on antenna size, but the nulls
