Abstract
This paper examines variants of a reflected signal angular coordinate meter using artificial neural networks for a frequency-agile radar based on an antenna array with subarrays, generating sum and difference channels, and an array of adapted receiving channels near the observation direction. A model of amplitude-phase- frequency non-identities of receiving channels during frequency agility and angular scanning is developed. Neural network architectures are proposed based on a multilayer perceptron for the case of creating sum-and-difference channels and a complex convolutional neural network and a multilayer perceptron for generating an array of adapted receiving channels. Modeling shows that the proposed architectures ensure the almost complete elimination of angular coordinate estimation errors associated with the presence of amplitude-phase-frequency non-identities of receiving channels, with an estimation accuracy close to the potentially achievable one.
