You may notice that a single branch of this architecture is similar to a Convolutional Neural Network (CNN) used in computer vision. This is because the architecture involves both a generator and a discriminator model that compete in a zero-sum game. A good training session will have moderate (~ 0.5) and relatively stable losses for the unsupervised discriminator and generator while the supervised discriminator will converge to a very low loss (< 0.1) with high accuracy (> 95%) on the training set.

Both of these approaches are capable of learning and identifying the objects, but the execution is very different. In the radar case it could be either synthetically generated data (relying on the quality of the sensor model), or radar calibration data, generated in an anechoic chamber on known targets with a set of known sensors. We humans can detect various objects present in front of us and we also can identify all of them with accuracy. The supervised discriminator architecture is shown in the figure below and you may notice its similar to the DNN architecture shown nearby, with some exceptions including the use of LeakyReLU (Leaky Rectified Linear Unit) instead of ReLU which is a GAN training best practice [7].
