Model for standard moment autocorrelations

The model for the moment autocorrelation calculations is as follows (using R0 as an example):

R 0 h h = g h r g h t S ′ h h + N h
R 0 v v = g t r g v t S ′ v v + N v
R0 hh, R0 vh, R0 vv, R0hv
The autocorrelations of the samples at lag 0.
Shh, Svh, Svv, Shv
The average power returned from the scatterers.
grh, grv
Receiver gains for horizontal and vertical receive.
gth’ gtv
Transmitter gains for horizontal and vertical transmit.
Nh, Nv
Measured noise power of the samples.

The power that is measured in a channel has comprises:

  • Backscattered power from the targets that is effected by the transmitter and receiver channel gains
  • Receiver noise, which is measured by RVP10 during noise sampling

In R1 and R2 autocorrelations, the model is similar, except there is no noise bias.
