Modeling Of Power Management On Airborne Fire-control Radar In Typical Working Modes

The improving performance of modern airborne weapons and the complication of the battlefield environment lead to more highly demand to airborne fire-control radar. In order to achieve the goal of “Discover first, Attack first, Destroy first”, airborne fire-control radars are developing fast recent years, and now have become indispensable equipment for a modern air force in process of air battle. The applications of new techniques like AESA extended the functions and enhanced the performance of airborne fire-control radar, but also occupied the limited radar resources. Therefore, it is crucial to study how to optimize resource management and play a maximum effectiveness considering the requirement of multitasks and data rate.Based on the existing methods and models for resource management of phased array systems, this article focuses on the special technology on working mode management and power management. The fundamentals of working mode management and power management are deeply analyzed from technical and tactical view. And a method of resource management is given at the theoretical level, while a relatively complete mathematical model is constructed at the engineering level. A simulation is also made to test them.The main content is divided into four parts:Firstly, background and significance of this research is pointed out. The research status is introduced from three parts: working mode management, power management and simulation technology on airborne radar. The main work and structure arrangement of this article is also summarized.Secondly, the working modes of airborne radars are studied and modeled. The signal processing of search/intercept and track under the three PRF modes of signal is analyzed. The typical working modes under A-A and A-S situation are modeled. According to the tactical background, the use policy and typical parameters are also modeled. The models above come up to a relatively complete method of working mode management on airborne radar which is close to combat factors.Thirdly, the management of power on airborne radar is studied and modeled. The fundamentals of power management are discussed, the “5 Domains” conditions of interception are analyzed, and the common expression for interception probability is given. Then the factors which can influence interception probability and power management strategy are analyzed from both radar system and target type. A four-step flow of power management is designed and modeled. Basing on that, a set of methods for power management on airborne radar which combine as much as campaign situations are concluded.Lastly, a simulation is carried out to power management under typical working modes to test the working mode management and power management. Combining target types and radar systems, 4 representative working modes are picked out and their power managements are modeled. Two simulation scenarios under the situation of A-A and A-E are made. Simulations are also carried out to the power management during the whole process. The result shows that the research above are as expected and the models are of high reliability.The methods and mathematic models of working mode management and power management on airborne fire-control radar are presented in this article. An implementation method of power management on airborne fire-control radar is given and the mathematical model and simulation model are established. The simulation result shows that the methods are feasible and effective. The research can improve the theoretical system of radar EW modeling and simulation, provide technical storage for the development of airborne fire-control radar, and provide support to the relevant simulation and evaluation system.
