Design Of Fuse Doppler Signal Acquisition Test System Based On Microcomputer

With the development of society, the fuze acquisition test system in the study of weaponsystem has become more and more important. At present, because of the odious testenvironment and test conditions, and the test data cannot be collected from the target signalcable transmission. This paper presents a design method of fuze Doppler signal acquisitionand wireless communication test system based on microcomputer.Based on the relevant literature, a new fuse Doppler signal test system based onC8051F340microcomputer was designed. This paper mainly completed the design of thewhole test system hardware design and software. The overall system is divided into severalmodules. Firstly，This paper introduced the acquisition of the target signal, it is mainly theDoppler signal received by the fuze, with EL8201as the signal processing module, the signalprocessing input to the microcontroller, microcontroller after the completion of A/Dconversion, temporarily stored in the data memory of single-chip computer, prepared by thewireless module to transmit. Secondly, this paper introduced the design for the system ofwireless transmission module, the design chooses nRF24L01as wireless RF chip, andcompleted the wireless module and MCU communication circuit design of hardware circuitand software program. Finally, under the experimental conditions, this paper completed thedata correctness verification experiment of target signal acquisition and wirelesstransmission.In the last，the whole system debugging is completed. This paper completed staticexperiment of Doppler signal acquisition and wireless transmission of the system, simulationtest field also rendezvous in missile target in the simulated Doppler signal dynamic test. Aftercompletion of the test, analyzing the frequency spectrum，The test results show that: the analysis are consistent with the theoretical calculation values.
