Abstract Target detection is an important research content in the radar field. At present, efforts are being made to optimize the precision of detection information. In this paper, we use the high pulse repetition frequency (HPRF) transmission method and orthogonal biphase coded signals in each pulse to avoid velocity ambiguity and range ambiguity of radar detection. In addition, We also apply Walsh matrix and genetic algorithm (GA) to generate satisfying orthogonal biphase coded signals with low auto-correlation sidelobe peak and cross-correlation peak, which make the results more accurate. In a radar receiver, data rearrangement of echo More >

Abstract Water injection has shown to be one of the most successful, efficient, and cost-effective reservoir management strategies. By re-injecting treated and filtered water into reservoirs, this approach can help maintain reservoir pressure, increase hydrocarbon output, and reduce the environmental effect. The goal of this project is to create a water injection model utilizing Eclipse reservoir simulation software to better understand water injection methods for reservoir pressure maintenance. A basic reservoir model is utilized in this investigation. For simulation designs, the reservoir length, breadth, and thickness may be changed to different levels. The water-oil contact was More >

Abstract Since the 21st century, the Internet has been updated and developed at an alarming speed. At the same time, WeChat applets are constantly improving and introducing new functions. Develop an enterprise recruitment system based on WeChat applets for the majority of job seekers and recruiter users, provide job seekers with easy-to-reach employment opportunities, and provide a convenient and clear screening environment for job seekers. The front-end part of the applet is developed using WeChat developer tools, and the back-end system is developed using MyEclipse. Use Spring Boot + Spring MVC framework, implemented in Java language.
