Using Fig. 9.73, which depicts the geometry of the Shuttle radar interferometer, show that

z(x) = h - r1 cos θ

Then use the Law of Cosines to establish that Eq. (9.108) is correct.

(A$/2)? – a² 2a sin (α - θ ) -( φ/2π) cos 0 (9.108) z(x) = h

Fig. 9.73

P2 Z. P1 90-0 r2 s\z(x) х

(A$/2)? a 2a sin ( - ) -( /2) cos 0 (9.108) z(x) = h P2 Z. P1 90-0 r2 s\z(x)
