Phased Array Design Toolbox v2.5

References to 'bessel' functions in the taywin_array and related functions changed to besselj. Older versions of Matlab assume bessel is 1st order by default, so didn't flag an error.

Correction to the exspinlin2.m example and the cpol_array.m help info. The cpol_array parameters for generating RHCP/LCHP changed when the phase lead/lag definition was changed for v2.5. The code itself hasn't altered.

Had a few connection problems today, uploaded again to be sure.

A few minor typo's corrected, mainly in the help text of the examples, no changes to the code itself.

Uploaded without toolbox option checked, hopefully to remove the 'required products' that appeared in the previous upload.

Just noticed there were lots of extra required products listed, I didn't add them, still just Matlab itself.

In this update, near-field analysis and calculation of absolute values for gain and radiated field quantities have been added. See the : ‘Change Log’, ‘FAQ’ and ‘What’s new in ArrayCalc v2.5’ in the documentation folder for details.

I found a problem with statistical variation functions plot_theta_statvar and plot_phi_statvar. The random errors were not being applied to all array elements. Apologies for any confusion / inconvenience caused.

All filenames have been changed to lower case, hopefully improving compatibility with later versions of Matlab. There is also additional information on phased array and phase shifter design, as I get many questions on this.

A couple of minor changes to the interp_geom.m file. Some sub-array and reflector modelling examples added

Some new functions added to combine 3D array geometry and 3D patterns on the same plot.
A full user guide is now included.
See changelog.txt for details.

Couple of typo's in help files corrected.

Comments and help added to and tidied up.
Examples moved to separate directory.
Fourier beam synthesis added together with examples, see changelog.txt for details.

Help and comments added to and minor corrections made.
Examples moved to separate directory.
Fourier beam synthesis added, with examples - see changelog.txt

Very minor, place_element.m was reporting angle rather than position in the text commentary to screen (Placing element number... etc). No effect on calculations.

3D Pattern routines re-written, functionally the same but hopefully easier to follow and a bit more robust.see changelog.txt for details.

More examples added illustrating different applications and limits of operation.

General tidying and corrections of help files and comments, rather a lot actually, so apologies for that.

Element excitation error analysis added, see changelog.txt

Circular Polarization analysis added.
Aperture Element models added.
See changelog.txt for details.

Version1.1 is still available at activefrance.com

Some minor corrections, mainly typos in comment/help files.
