Figure 2.3: Wan Q is mbdivided into rn x n subregions, where each subregion,
ij, is mmitmed by the radar to give a radial mmponent u,- dong the $ direction
and the tt"udistant cell from the radar.
where n be- interset the region and A#, is the beamwidth of be- number I.
This geometry is shown in Figure 2.3.
Let them range cells within 4 be indexed from 0 to m - 1 and let a rage cell
within this range be indexed by i. Let's mnsider the radial current from the tjLh eeu,
where j is the index of the beam which makes an angle 8, with the x--. Sice
this current obtained from an actual radar system consists of an error mmponent,
e,,, equation (2.7) may be remtten a~
