A simple GUI tool for antenna array analysis

Hi there 👋

I am Dr. Zhengyu Peng, a senior radar systems engineer with a strong background in radar systems. I received my Ph.D. from Texas Tech University in 2018 and have been heavily involved in the development of high resolution imaging radar at Aptiv, a company focused on creating safer and more sustainable mobility solutions. My areas of expertise include automotive radar, radar signal processing, mm-wave and microwave systems, antenna arrays, and beamforming. I am also an associate editor for the IEEE Transactions on Instrumentation and Measurement and a member of the SPIE Defense+Commercial Sensing Radar Sensor Technology Committee.

antenna-array-analysis's Issues

Add export plot data function

'antarray' module isn't included

There is a dependency on the antarray module, but this isn't a known PyPi module. A folder named antarray/ is included in .gitignore and has not been submitted with this repository.

Can you provide insight into how to obtain the antarray module?

Add "About" menu

How can I save your phase data?

Your work is outstanding! I tried to save the patch and phase configuration in Windows 10, but the .csv file is not displayed(Not saved successfully) in the specified directory. I think you might know how to solve this problem.

Thank you

great job

Thank you very much for this resource

Feature request: hybrid antenna arrays with independent analog/digital steering

Thank you for this useful software, @rookiepeng.

I'd like to propose a valuable, seemingly incremental feature: hybrid arrays. Since hybrid beamforming was proposed, most people disregard the problems of exchanging single elements by subarrays, the main one being the large side lobes. As such, visualizing antenna patterns of such arrays would be very beneficial.

I'd deconstruct this feature as:
a) saving a previously designed phased array;
b) using that array as the radiating element of a new phased array;
c) besides allowing array-level beam steering (already supported), allow beam steering also on the subarray level.

Add export array config menu

Feature request: 3D radiation patterns

Once again, @rookiepeng, thank you for this valuable python package.

This feature has certainly crossed your mind. Instead of the azimuth and elevation cuts, having the 3D radiation pattern version.

Motivation: it would massively boost the array pattern interpretability and overall array understanding, far beyond what is possible with azimuth and elevation cuts.

I would further consider different 3D antenna placements in the XoZ plane, with x-axis pointing at us (perpendicular to the 2D view), the y-axis pointing from left to right, and z-axis from bottom to the top. This would be useful because vertical array deployments are the most common for most applications, namely sensing and communications.

Hold plot function is broken

QGraphicsEllipseItem class now belongs to QtWidgets

After the installation of all the required packages from scratch and running arrayanalysis.py, an error was thrown at line 265, in init_figure:

    QtGui.QGraphicsEllipseItem(
AttributeError: module 'PyQt5.QtGui' has no attribute 'QGraphicsEllipseItem'

Replacing QtGui with QtWidgets seems to solve the issue.

self.circleList.append(
                QtWidgets.QGraphicsEllipseItem(
                    -self.polarAmpOffset + self.polarAmpOffset / 6 *
                    circle_idx,
                    -self.polarAmpOffset + self.polarAmpOffset / 6 *
                    circle_idx,
                    (self.polarAmpOffset - self.polarAmpOffset / 6 *
                     circle_idx) * 2,
                    (self.polarAmpOffset - self.polarAmpOffset / 6 *
                     circle_idx) * 2))

non-uniformly distributed array feature required
