Abstract: In some examples, measurement data is received from at least one sensor that detects a signal reflected from a surface inside a platform. A likelihood ratio test is applied using the measurement data, and a load status of the platform is determined based on the likelihood ratio test.

Abstract: Based on a relationship between measurement data from at least one sensor and a baseline, a load status of a platform is determined. In response to the determined load status, such as determining that the platform is empty, the baseline is refined using a baseline estimator to produce a refined baseline that can be used to determine a further load status of the platform.
