[Abstract]:This paper focuses on the irreplaceable melee role of short-range battlefield alert radar and its increasingly prominent tactical significance in current military operations, combining with the in-depth and systematic study of the linear frequency modulation continuous wave (LFMCW) system. In this paper, the feasibility of the application of LFMCW in short-range battlefield warning radar is analyzed, and the problems of ranging and velocity measurement, moving target detection and multi-target signal processing are studied deeply. Finally, the functional and technical indexes of the experimental prototype are designed, and the situation of each functional module is analyzed. The purpose of this paper is to combine the target detection algorithm and the frequency domain pairing algorithm to solve the problem of multi-target detection according to the characteristics of LFMCW system. As a result, the short-range battlefield alert radar of this system can be applied to the front line of the current military struggle, and can meet the needs of the combat units for front-line surveillance, single-soldier reconnaissance, border and coastal defense, and military guarding. Moreover, it has a continuous operation and is simple to operate. It can meet the requirements of miniaturization, lightness, low cost, high performance and so on, so it is convenient to equip a large number of front-line troops. In contrast, LFMCW radar has good anti-interception performance, high range resolution, strong anti-jamming ability, low peak power, no range blind area, small and light structure and excellent short-range performance, so it can be used in short-range warning. The feasibility and correctness of the method are proved by the analysis and simulation experiments. The main research work of this paper is as follows: 1. The background and significance of short-range battlefield alert radar are expounded, and the research and development situation and technical system characteristics of this kind of equipment are analyzed and discussed. The development trend of the radar is also introduced. The application scene and target detection principle of short-range battlefield alert radar are analyzed, and its working principle is studied in detail. Finally, the simulation of target detection algorithm is carried out. The correctness and feasibility of the signal processing method in this paper are verified, and the full reference data. 3 is provided for the following analysis. The signal processing process of LFMCW radar is studied. The frequency domain pairing processing method of multi-target detection is analyzed and studied in detail. The effectiveness of the method in multi-target detection is verified by simulation. The function and index parameters of the prototype experimental system are given. A suitable signal processing scheme is selected, and the algorithm is explained and analyzed. Finally, the thesis systematically summarizes the work of the paper, and makes clear the problems that need further research and analysis in the future.
