The aim is to enhance radar target detection in complex environments disrupted by clutter through deep subspace methods.
Utilized deep subspace autoencoders to decompose radar data into low-dimensional subspaces.
Developed a parallel array of autoencoders to adaptively analyze local statistical properties.
Implemented an anomaly scoring mechanism integrated with various analysis methods.
Employed an adaptive threshold based on data distribution for improved detection accuracy.
The proposed method showed significant improvements compared to traditional detection approaches.
Demonstrated better performance in complex simulations with various clutter types and target dynamics.
Achieved a maintained false alarm rate, enhancing robustness in detection scenarios.
