FIGURE 6-45.-Effect of pointing-angle variations on radar returns normalized to unity. (a) "Flat sea" return for no jitter. Height is 435 km (235 n. mi.). (b) Comparison of measured mean return and theoretical return for a 100-nanosecond transmitted pulse-width (pointing angle 0.5° off-nadir). Error bars are based on one standard deviation Greek letter sigma.
