| This research presented investigates the radar and main control key techniques that based on sub-task "Multi-sensor Vehicle Based Battlefield Information Acquisition System" in National 973 project "New Mechanism, New Method Research for Automatic Radar Target Recognition".The design of the Multi-sensor Vehicle Based Battlefield Information Acquisition System is performed. The functional models of main control system and three subsystems which are radar, MW-IR/LW-IR and visible light are investigated. Based on the analysis of the network communicate characteristics among the subsystems, a network communication protocol is given with research, which is both canonical and expandable.For the characteristics of the millimeter radar, the LFM signal is used to get larger time-bandwidth. The investigation of the sidelobe and sidelobe suppression for the LFM signal is given. An adaptive double threshold detection method is presented, while the use of it gives better performances for the detection in the radar subsystem, such as the higher detection probability and the lower faise alarm probability. The implement with C# language of the radar subsystem is shown.Based on the top-level design idea and the modularization principle, the design and modularization of the main control system is proposed to meet the demand. The flow is planned detailed with the characteristic of the vehicle based system. The implement with C# language of the main control subsystem is shown. |
