1. 1. Noise Robustness of Convolutional Autoencoders and Neural Networks for LPI Radar Classification

   Master-uppsats, KTH/Matematisk statistik

   Författare :Gustav Norén; [2020]
   Nyckelord :LPI radar; CNN; autoencoder; noise robustness; denoising; LPI radar; CNN; autoencoder; brustålighet; avbrusning;

   Sammanfattning : This study evaluates noise robustness of convolutional autoencoders and neural networks for classification of Low Probability of Intercept (LPI) radar modulation type. Specifically, a number of different neural network architectures are tested in four different synthetic noise environments. LÄS MER

   Sammanfattning : Radar signals are used for estimating location, speed and direction of an object. Some radars emit pulses, while others emit a continuous wave. Both types of radars emit signals according to some pattern; a pulse radar, for example, emits pulses with a specific time interval between pulses. LÄS MER
