Weakly supervised object localization (WSOL), which trains models using solely image category annotations, remains a challenging problem. Existing approaches based on convolutional neural networks (CNNs) tend to miss full extent while activating discriminative parts. Based our analysis, this is caused by CNN's intrinsic characteristics, experiences difficulty capture semantics at long distances. In article, we introduce the vision transformer WSOL, with aim long-range semantic dependency of...
Effective ground stationary operational target detection is the precondition of subsequent identification for helicopter-borne fire-controlled radar. More abundant information could be obtained when adopting wide-band radar than traditional narrow-band one. While there exit such problem high false alarm and poor adaptability applying methods. Thus, a novel method airborne based on statistical characteristic presented in this paper. By considering distribution property both range azimuth...
This letter presents a non-probabilistic interval-based calculation method for antenna performance evaluation. After the interval function of far field pattern is given, process complex exponential deduced. Then power affected by distortion errors derived in accordance with operation rules. The applied to an 8-meter as numerical example.
