Symbol Description Units Status

win window for sidelobe control none input

nbits negative #: perfect quantization none input

2 nbits positive #: use quantization levels

patterng gain pattern dB output

amn a(m,n) sequence defined in Eq. (8.68) none output

Figs. 8.44 t hrough 8.49 respectively show plots of the array gain pattern ver-
sus steering for the following cases:

[pattern, amn] = circ_array(15, 0.5, 0.5, 0, 0, -1, -1, -3)

(8.79)

[pattern, amn] = circ_array(15, 0.5, 0.5, 20, 30, -1, -1, -3)

(8.80)

[pattern, amn] = circ_array(15, 0.5, 0.5, 30, 30, 1, ÒHammingÓ, -3)

(8.81)

[pattern, amn] = circ_array(15, 0.5, 0.5, 30, 30, -1, -1, 3)

(8.82)

[pattern, amn] = circ_array(15, 1, 0.5, 10, 30, -1, -1, -3)

(8.83)

[pattern, amn] = circ_array(15, 1, 1, 0, 0, -1, -1, -3) (8.84)
Note the function Ðcirc_array.mÑ uses the function Ðrec_to_circ.mÑ, which
computes the array amn ( , ) . It is given in Listing 8.7 in Section 8.8.

The MATLAB GUI workspace defined in Ðarray.mÑ can be used to execute
this function.
