    Syntax

    elres = rainelres(r,beamw,grazang)
    elres = rainelres(r,beamw,grazang,hgt)

    Description

    example

    elres = rainelres(r,beamw,grazang) returns the elevation resolution of rain limited by the resolution of the radar.

    example

    elres = rainelres(r,beamw,grazang,hgt) also specifies the height extent of rain.

    Estimate the elevation resolution of rain for a side-looking airborne synthetic aperture radar (SAR) with elevation beamwidth of 9∘ grazing at 60∘ for a target range of 10 km. Assume the height extent of rain to be 3 km.

    elbw = 9;
grazang = 60;

rng = 10e3;
hrain = 3000;

    Compute the rain elevation resolution.

    elres = rainelres(rng,elbw,grazang,hrain)
    elres = 782.1723

    Input Arguments

    collapse all

    Range from target to antenna in meters, specified as a positive real scalar or a vector.

    Data Types: double

    Elevation beamwidth in degrees, specified as a positive real scalar or a vector.

    Data Types: double

    Grazing angle in degrees, specified as a scalar in the range [0, 90].

    Data Types: double

    Height extent of rain in meters, specified as a real scalar.

    Data Types: double

    Output Arguments

    collapse all

    Elevation resolution of rain, returned as a matrix. The rows of elres correspond to the range values in r and its columns correspond to the elevation beamwidth values in beamw.
