Senior Design Plan

Project Overview:

Our project aims to use Software-Defined Radios (SDRs) for signal detection in a specific area. We'll initially simulate SDR behavior in MATLAB before practical implementation. Once the antennas are identified, we plan to refine signal location by deploying additional SDRs along the detected path.

Steps:

Choose antennas for SDRs.

Simulate SDR behavior in MATLAB.

Implement SDRs in the real world for signal detection.

Develop code to parse and utilize SDR-detected locations.

Teams:

Hardware: Ensure successful SDR communication and design necessary circuitry.

Localization: Aggregate data from SDRs to identify transmitter points.

Visualization: Create a 3D representation and a user-friendly GUI.

Design Concepts:

Support multiple localization inputs (e.g., 3D SDRs, fox-ears method, RADAR, Wi-Fi).

Continuously update the 3D space with changing signal locations and strengths.

Integrate terrain data for improved contextualization.

Design a sleek and intuitive GUI for easy analysis by technical beginners.

Project Testing Overview:

We'll test hardware components by ensuring SDRs can reliably send and receive signals on a single frequency band. The chosen test signal will be a low-power sub-GHz signal to minimize interference in real-world scenarios. For the software, our goal is to develop code that parses signals, extracts position data and estimates locations in 3D space. This involves loading positional data matrices from each SDR, matching associated signals, and determining positions. To assess the MATLAB visualization, we'll begin with simulating a stationary test signal in the graphic user interface. This will progress to testing moving signals and eventually multiple simultaneous moving signals.
