Fundamental Algorithms for Target Localization

This document provides comprehensive details about fundamental target localization algorithms, covering Centroid Algorithm, RSSI (Received Signal Strength Indicator) Algorithm, TOA (Time of Arrival) Algorithm, and AOA (Angle of Arrival) Algorithm. Each algorithm employs distinct localization principles and techniques, offering unique advantages and application scenarios. During implementation, we conducted multiple debugging cycles and optimization procedures to ensure all programs function correctly. The Centroid Algorithm calculates the geometric center of reference points using coordinate averaging, while RSSI implements signal strength-to-distance conversion with path loss models. TOA algorithms employ time measurement techniques with trilateration, and AOA utilizes angle detection methods through triangulation. Through extensive simulation experiments, we obtained detailed results and data that validate the effectiveness and accuracy of these algorithms. The code includes key functions for signal processing, coordinate calculation, and error analysis, ensuring reliable performance across various test scenarios.
