ASTF

This project is named with ASTF, Abstracted Signal Time-Frequency Diagram. ASTF is a newly designed visualization diagram that can depict the long-term (i.e., hours, 1-2 days, and even 1-2 weeks) time-varying patterns of radio signals to fulfill long-term signal analysis requirements in radio monitoring and management scenarios.

Dependencies

This project adopts a front-back separation technology. The front-end adopts a Vue framework and the back-end adopts a Flask framework. The running environments include:

• Python 3.7.7
• Node 14.16.1

Other dependencies can be installed through commands. Specifically, the front-end dependencies need to execute the following commands:

cd view
npm install

The back-end dependencies need to execute the following commands:

cd server
pip install -r requirements.txt

Usage

We provide two simple datasets for testing.

1. Start the front-end service

You can start the front-end service by executing the following commands:

cd view 
npm run serve

2. Start the back-end service

You can start the back-end service by executing the following commands:

cd server
python app.py

3. Open the URL

Open a browser and enter the following URL address: http://localhost:8080/
