چکیده

With the development of digital radio frequency memory technology, main-lobe deception jamming represented by interrupted-sampling repeater (ISRJ) poses a severe challenge to radar. Traditional antijamming methods usually need estimate parameters and have risk losing target information. For above problems, this article proposes deep neural network-based ISRJ recognition detection method which consists four serial steps. First, proposed obtains time-frequency image set radar echoes short-time Fourier transform (STFT). Second, you-only-look-once (YOLO) model is used detect jammed echoes, positioning result automatically corrected avoid Third, anti-ISRJ ranging velocity measurement datasets are constructed according result. Finally, an based on convolution network (CNN) designed extract features along different dimensions obtain range real targets. Experiments simulated measured show that has better performance than traditional method, does not parameters.

An Adaptive Transmitting Scheme for Interrupted Sampling Repeater Jamming Suppression

The interrupted sampling repeater jamming (ISRJ) based on a digital radio frequency memory (DRFM) device is a new type of coherent jamming. This kind of jamming usually occurs as main-lobe jamming and has the advantages of low power requirements and easy parameter adjustment, posing a serious threat to the modern radar systems. In order to suppress the ISRJ, this paper proposes an adaptive tran...

A conjugate gradient based method for Decision Neural Network training

Decision Neural Network is a new approach for solving multi-objective decision-making problems based on artificial neural networks. Using inaccurate evaluation data, network training has improved and the number of educational data sets has decreased. The available training method is based on the gradient decent method (BP). One of its limitations is related to its convergence speed. Therefore,...

Deceptive Opinion Spam Detection Using Neural Network

Deceptive opinion spam detection has attracted significant attention from both business and research communities. Existing approaches are based on manual discrete features, which can capture linguistic and psychological cues. However, such features fail to encode the semantic meaning of a document from the discourse perspective, which limits the performance. In this paper, we empirically explor...
