As the world continues to explore space through aeronautics, rocket launch activities have become more frequent. However, the existing debris tracking methods are limited by inaccurate precision and high cost, so a more efficient, precise, and economical tracking technology has become the current research focus. This paper studies the spatial positioning of single and multiple debris separately. The mathematical model for single debris positioning is established based on the multi-side measurement model and the time difference of arrival, and the accurate value is obtained by optimizing it using the least squares method. The multi-debris positioning method takes the data matching approach, matching the series of vibration waves received by the monitoring equipment with the debris, optimizing the single debris positioning mathematical model, and obtaining precise data through the Hungarian Algorithm optimization. Based on the known data, the relative position of the debris to detector A is calculated as 37947.7463 meters east, 5801.3071 meters south, and 963.2116 meters high, with the sound wave occurring 6.5357 seconds earlier than the actual.
