The Python folder contains the Python scripts for control over the transducer stages (controller.py and main.py). Furthermore, the Python scripts for sampling of the microphone signal (daq.py), ...

Earlier phased array radars only used one phase shifter per element (or per group of say 4 elements or so, known as a sub-array), nothing active. There are different levels of complexity.

Python Improve this page Add a description, image, and links to the phased-array topic page so that developers can more easily learn about it.

Today phased arrays are in all sorts of radio equipment from broadcast radio transmitters to WiFi routers and 5G phones. The technique even has uses in optics and acoustics.

The phased-microphone array provides a means for clients to examine the aeroacoustic signature of their model in a controlled test environment. It consists of a 96-channel data acquisition system ...

Active Electronically Scanned Arrays (AESAs) used in radar systems typically use digital receiver exciters (DREX) units. Functional testing of DREX units can be challenging due to their complexity.
