[Abstract]:Meter-wave radar has the advantage of anti-stealth, but the contradiction between angle measurement accuracy and maneuverability limits the development of Meter-wave radar. In order to solve the above contradiction, this project adopts the method of distributed array coherent synthesis, and builds a fully digital distributed meter wave radar test system, carries out the field test, and makes the theoretical method through the measured data. The key technology and main performance indexes were tested and verified. The radar system consists of two array antennas (8 antennas per group), two correction networks, two DAM modules, a timing control board module, a display and control software, a data collector and a signal processing board. The modes of operation include transmit correction, receive correction, mode, equal T search, variable T search, orthogonal step frequency, step frequency coherent, orthogonal phase coding and coherent phase coding mode. In this paper, the author is mainly responsible for the display and control software development of the radar system and the design of the communication program of the network port of the timing control board. The display and control software is used to control the entire radar system. Because the running platform of display control software is PC's Windows operating system, and considering the efficiency of software development, this paper chooses VC 6.0 as the software development platform, and realizes the software development using MFC class library and C language coding. According to the working requirements of radar system and from the point of view of software engineering, the function requirement, data requirement, interface requirement and reliability requirement of the display and control software are analyzed, and the development flow of the display and control software is determined. Based on the software design idea of modularization and gradual refinement, the overall design scheme of display and control software is established. The software is divided into three main functional modules: input, output and network port communication, and each module is further refined. Divided into a plurality of sub-function modules. The input module mainly completes the selection of working mode, array parameter setting, DAM parameter setting, correcting network error coefficient import, DBF parameter setting, DAM channel setting, transmitting channel setting, etc. The network port communication module is mainly used to realize the data transmission between the display and control software and the timing control board, and the output module mainly realizes the array position of the radar system. The display of the result of the transceiver correction and the location of the target, as well as the function of the derivation of the transceiver correction coefficient; The method of joint debugging is used to test the display and control software, and the result verifies the correctness of the design and development of the wire control software. Finally, the basic principle of network port communication is introduced, including the structure model of Ethernet, the layering of TCP/IP protocol, the encapsulation of TCP/IP protocol and the separation of TCP/IP protocol. The network port communication module of the timing control board uses DP83865 and FPGA as the hardware platform, in which DP83865 is responsible for realizing the function of physical layer, and FPGA is mainly responsible for the process of data packing, unpacking and checking. The process can be divided into two parts: MAC core configuration and TCP/IP protocol coding. The physical layer chip and the MAC core adopt MII interface for data transmission. The receiving channel and transmission channel are independent of each other. The data bit width is 4 bits and the transmission rate can reach 100 Mbpss. The data encapsulation and packet unpacking of each layer of TCP/IP protocol are realized by using Verilog language coding, thus realizing the communication function of network port of timing control board.
