DeepDOA

An implementation of a Sparse Denoising Autoencoder (SDAE)-based Deep Neural Network (DNN) for direction finding (DF) of small unmanned aerial vehicles (UAVs). It is motivated by the practical challenges associated with classical DF algorithms such as MUSIC and ESPRIT.

The proposed DF scheme is practical and low-complex in the sense that a phase synchronization mechanism, an antenna calibration mechanism, and the analytical model of the antenna radiation pattern are not essential. Also, the proposed DF method can be implemented using a single-channel RF receiver.

Architecture training phase:

Dependencies

  • Tensorflow (recommended below 1.5)
  • Numpy 1.14.4

Dataset

A partial dataset is provided to demonstrate our method training data : Dround_Data_New/Normalized testing data : Dround_Data_New/Normalized_test

data are categorized according to 45 degree sectors in training/testing data eg : 'deg_0_normalize.csv' data file represent the training data collected from the first sector and like wise there are 8 sectors considered for this study

For more details, please see our paper below.

File description

  • DNN_Ground_data_8sectors.py : Implementation without SDAE
  • DenoisingAE.py : Implementation of SDAE for training it separately to learn denoising features.
  • get_csv_data.py : Data handler
  • main.py : combining SDAE with a neural network to perform DOA estimations
