Description
Examples
Swath Length and Width
Estimate the maximum swath length and width of side-looking airborne synthetic aperture radar (SAR) operating at 16.7 GHz for a target range of 10 km. The radar has an aperture length of 3 m in the elevation dimension and of 4 m in the azimuth dimension. Assume a nominal grazing angle of .
lambda = freq2wavelen(16.7e9); R = 10e3; elaz = [3 4]; grazang = 30;
Compute the swath length and the swath width.
[swl,swwid] = aperture2swath(R,lambda,elaz,grazang)
swl = 119.6776
swwid = 44.8791
Input Arguments
r
— Range from target to antenna
positive real scalar | vector
Range from target to antenna in meters, specified as a positive real scalar or a vector.
Data Types: double
lambda
— Radar wavelength
positive real scalar | vector
Radar wavelength in meters, specified as a positive real scalar or a vector.
Data Types: double
d
— Antenna dimensions
positive real scalar | 1-by-2 row vector
Antenna dimensions in meters, specified as a positive real scalar or a 1-by-2 row vector.
If you specify
d
as a two-element vector, the first element ofd
represents the antenna dimension in elevation and the second element represents the antenna dimension in azimuth.If you specify
d
as a scalar,aperture2swath
assumes the antenna has equal elevation and azimuth dimensions.
Data Types: double
grazang
— Grazing angle
scalar in the range [0
, 90
]
Grazing angle in degrees, specified as a scalar in the range [0
,
90
].
Data Types: double
Output Arguments
swlen
, swwidth
— Swath length and width
matrices
Swath length and width in meters, returned as matrices.
The swath width also corresponds to the azimuth or cross-range resolution of a real aperture antenna.
