Abstract: New-generation phased array radars (PARs) are critical components of early warning and surveillance systems, playing pivotal roles in major national defense and civil infrastructure projects. As radar equipment evolves towards higher levels of integration, exhibiting characteristics such as high coupling of electromechanical-hydraulic-magnetic systems, structural-functional integration, and multiple generations of electronics on a single platform, it imposes more stringent requirements on quality control throughout the entire development process. This paper systematically analyzes challenges and deficiencies in quality management during the four phases of Production, Alignment, Measurement, and Evaluation (P-A-M-E) for phased array radars. A targeted quality control methodology encompassing P-A-M-E across the full development cycle is proposed. Subsequently, quality control technologies with intelligentization as the driving thread are introduced. The paper concludes with an analysis of P-A-M-E implementation at a representative radar enterprise, providing insights for deploying novel technologies, applications, and management models in complex electronic systems quality control.
