Abstract: The conventional moving target indicator (MTI) radars perform doppler processing using MTI filters and FFT filter bank for ground clutter rejection and estimating the moving target parameters. The MTI radar suffers from clutter ridges at zero-doppler frequency. MTI filters are used to remove these clutter ridges, but MTI filters introduce the blind speeds. If phased array antennas are used to electronically scan the beam, Space Time Adaptive Processing (STAP) can be spatially filter out the clutter. In this work, a staggered pulse repetition....

Abstract: The article discusses the theoretical, methodological, and technological aspects of integrating artificial intelligence into the structure of modern digital teaching materials in the context of the digitalization of higher education in 2025–2026. It is argued that digital teaching materials are transforming from static electronic resources into multi-component intelligent educational...
