frequencies’ calculation
principle of multiple-beam
DSDM
f D =
2
λ 0
W cos η k ,
(17.1)
where λ 0 —wavelength of emitted oscillation, η—angle between flight-path velocity
vector and direction of sighting beam.
Express (17.1) via projections of flight-path velocity vector:
f Dk =
2
λ 0
W x k x + W y k y + W z k z
,
(17.2)
where k x , k y , k z —projections of
k vector into corresponding axes.
By analogy with (17.2) for other beams
l,
m,
n can be written as follows:
