English | 中文简体

This repository contains the course materials for "Aircraft Information System Design" in the Aircraft Control and Information Engineering program.

Contents

The project includes two main parts:

Voice Signal Acquisition and Processing Design

• Utilize the built-in sound card of a computer to capture voice signals.

• Display the time-domain and frequency-domain plots of the voice signals.

• Apply digital filtering techniques to enhance the quality of the voice signals.

Perform time-frequency analysis (spectrogram) of the voice signals.

Signal Simulation Design for Aircraft Communication, Navigation, and Surveillance System based on SDR

Simulate the functionality of two-way communication using amplitude modulation (AM) or single-sideband modulation (SSB) techniques

• Gain an understanding of the basic principles of high-frequency/very high-frequency communication systems.

• Generate a data file to implement the transmission and reception of simulated signals.

Very High Frequency Omni-Directional Range (VOR) System Design Experiment

• Simulate the transmission and reception of signals between the aircraft and ground-based VOR systems.

• Implement the simulation of direction finding functionality. Generate standardized signals for different VOR relative bearings (various degrees).

Instrument Landing System (ILS) Design Experiment

• Simulate the interaction between the onboard ILS system and the ground-based ILS system.
• Perform simulation of heading and glide slope deviation measurements.

Air Traffic Control (ATC) Transponder System Design Experiment(not completed)

• Simulate the interaction between the onboard transponder system and the ground-based secondary radar system.
• Implement identification of interrogation and response pulses.

Implementation Approach

The project will utilize Software-Defined Radio (SDR) technology, which allows various communication modules to be implemented using software on a general-purpose hardware platform.
