Human activity recognition (HAR) has long been a question of great interest in anti-terrorism and other applications. In recent years, radar has been one of
the most widely used sensing modality of detecting human motion and have been extensively used for HAR. This paper researches on blocked human activity description method and deep learning recognition algorithm. In order to obtain the real-time nature of recognition under the condition of through-wall probing scenario, we proposes a range profile sequence driven FC-SLSTM-FC end-to-end model, which employ random crop training method. Based on the architecture above, we process the actual radar data, finally achieve an average accuracy of 97.6%
and real-time output with delay of only milliseconds.
