This function aids in battlefield situational awareness and the commander's decision on which countermeasures to employ. This dissertation aims to develop a deep ensemble model, recognizing the importance of a fast and precise classification based on a deep forest as an alternative to the parameter matching method. Four deep ensemble models and six of its base learners were built and evaluated to classify 52 emitters, using seven train/test datasets and two test datasets with noise, totalling 420 measurements of accuracy and classification speed. After analyzing these results, two deep ensemble models and their base learners were optimized, each for a different dataset, achieving 100% accuracy in a feature-engineered dataset and up to 98.358% in the original dataset. Regarding classification speed, the fastest models can classify 1000 records in 64ms, which may be acceptable in the real world. The experimental results of this approach reveal several advantages, making it a feasible alternative, including reduced dependency on ESM experts, ease of maintenance, quick to update, and high accuracy.engEnsemble methodsDeep architectureElectronic Support MeasuresClassificationSDG 8 - Decent work and economic growthSDG 9 - Industry, innovation and infrastructureSDG 17 - Partnerships for the goalsmaster thesis203391470
