Nowadays, modern radar systems increase their target detection capabilities by processing pulses coherently. On the other hand, digital radio frequency memory‐based modern jammers have the ability to work coherently and can deceive radars even with a very low effective radiated power. These jammers, which have the capability of storing the radar's pulse, can use the previous pulses that they have stored in their memory during the electronic deception, without waiting for the last pulse of the radar, in other words, before the new pulse is received. If the radar does not change its parameters from pulse to pulse, such smart jamming techniques applied in this way can be very effective. In this article, the authors propose to use a smart binary phase‐coding method for pulse compression radar as an electronic protection technique against repeater jamming. This approach further improves the target detection capability of modern radar systems, which use coherent integration in the receiver. The proposed method can provide high protection against digital radio frequency memory‐based repetitive range deception techniques without compromising the radar's target detection capability. In the simulations, the traditional approach in which the same code is used without changing from pulse‐to‐pulse, and the approach using code sets obtained by the smart binary phase‐coding method in intra‐pulse modulation are compared. The results show that the proposed method can significantly improve the isolation against deception jamming and the target detection capability simultaneously.

Radar systems are a topic of great interest, especially due to their extensive range of applications and ability to operate in all weather conditions. Modern radars have high requirements such as its resolution, accuracy and robustness, depending on the application. Noise Radar Technology (NRT) has the upper hand when compared to conventional radar technology in several characteristics. Its robustness to jamming, low Mutual Interference and low probability of intercept are good examples of these advantages. However, its signal processing is more complex than that associated to a conventional radar. Artificial Intelligence (AI)‐based signal processing is getting increasing attention from the research community. However, there is yet not much research on these methods for noise radar signal processing. The aim of the authors is to provide general information regarding the research performed on radar systems using AI and draw conclusions about the future of AI in noise radar. The authors introduce the use of AI‐based algorithms for NRT and provide results for its use.

“…More specifically, the data control board uses EPM570T144 [31] as the main control unit, and its main functions are to give control signals and to provide data paths. The control signals are the control commands and timing signals that are needed in data processing [13]. The data paths integrate arithmetic and logic units of multifunctional calculators [1], general‐purpose registers [2], data latches, and counters via a single bus architecture, and the data exchange is realized via bus 7‐0.…”

The Principles of Computer Composition" is an important and fundamental core course in computing education. Recently, significant advancements have been made for experimental instruments that are related to "The Principles of Computer Composition" for colleges in terms of their functions and performances. However, most instruments are old, prone to failure, and are rarely automated. Some experimental systems use field-programmable gate array (FPGA) or a complex programming logic device (CPLD); however, the systems still use numerous integrated discrete and small-scale chips, which limits the functionalities of FPGA or CPLD chips. It is difficult to reconfigure the logic in all aspects of the experiment, and only a limited part of the logic can be reconstructed. Meanwhile, simulation experiments alone are too abstract for students to intuitively understand the circuit structures of the hardware. To address these issues, a CPLD-based experiment system for the course "The Principles of Computer Composition" was designed. The proposed system has a flexible design with clear circuit structures and a high degree of automation and stability. In addition, it comes with multiple functions, including logic reconstruction. The test results prove that the proposed system can help students obtain a better understanding of the course content. The system meets the design goal, and it contributes to the development of computing education.
