说明: 波束图定义为当阵列输入为平面波时,阵列输出与平面波入射角的关系。阵列天线的方向图是全方向的,但阵列的输出经过加权求和后,却可以使阵列接受的方向增益聚集在一个方向上,相当于形成一个波束,(The wave beam chart defines to work as when array input for plane wave, array output and plane wave incidence angle relations. Array antennas s directional diagram is entire direction, but array output after weighting summation, actually may cause the directive gain which the array accepts to gather in a direction, is equal in forms wave beam, )

8-optimal_in_FRFTdomains
time-invariant degradation models and stationary
signals and noise, the classical Fourier domain Wiener
filter, which can be implemented in O(N logN) time, gives the
minimum mean-square-error estimate of the original undistorted
signal. For time-varying degradations and nonstationary processes,
however, the optimal linear estimate requires O(N2) time
for implementation. We consider filtering in fractional Fourier
domains, which enables significant reduction of the error compared
with ordinary Fourier domain filtering for certain types
of degradation and noise (especially of chirped nature), while
requiring only O(N logN) implementation time. Thus, improved
performance is achieved at no additional cost. Expressions for
the optimal filter functions in fractional domains are derived,
and several illustrative examples are given in which significant
reduction of the error (by a factor of 50) is obtained.
