az2broadside

Convert azimuth and elevation angle to broadside angle

Syntax

bsang = az2broadside(az)

bsang = az2broadside(az,el)

Description

bsang = az2broadside(az) returns the broadside angle, bsang, corresponding to the azimuth angle, az, and zero elevation angle. All angles are define with respect to the local coordinate system.

bsang = az2broadside(az,el) also specifies the elevation angle, el.

Examples

Convert Azimuth Angle to Broadside Angle

Return the broadside angle corresponding to 45° azimuth and 0° elevation.

bsang = az2broadside(45)

bsang = 45.0000

Convert Azimuth and Elevation to Broadside Angle

Return the broadside angle corresponding to 45° azimuth and 45° elevation.

bsang = az2broadside(45,45)

bsang = 30.0000

Convert Multiple Azimuth and Elevation Angles to Broadside Angles

Return broadside angles for 10 azimuth-elevation pairs.

az = (75:5:120)';
el = (45:5:90)';
bsang = az2broadside(az,el);

Input Arguments

az — Azimuth angle

scalar | vector of real values

Azimuth angle, specified as a scalar or vector of real values. Azimuth angles lie in the range from –180° to 180°. Units are in degrees.

Example: [35;20;-10]

el — Elevation angle

0 (default) | scalar | vector of real values

Elevation angle, specified as a scalar or vector. The elevation angle lie in the range from –90° to 90°. The length of el must equal the length of az. Units are in degrees.

Example: [5;2;-1]

Output Arguments

bsang — Broadside angle

scalar | vector of real values

Broadside angle, returned as a scalar or vector. The length of bsang equals the length of az. Units are in degrees.

More About

Broadside Angle

Broadside angles are useful in describing the response pattern of a uniform linear array (ULA).
