Deep Anomaly Detection with Attention (DADA): A Novel Approach for Identifying Multipath Interference in Radar Signals

Figure 2

Two-dimensional time–frequency images extracted using SPWVD. Subfigures (a–d) represent the time–frequency images of normal LFM, NLFM, BPSK, and QPSK signals, respectively. Subfigures (e–h) represent the time–frequency images of the corresponding multipath LFM, NLFM, BPSK, and QPSK signals, respectively.
