Abstract Modern radar systems become more complicated, it is difficult to use simple intuitive analysis method for processing, therefore, radar system simulation increasingly get promotion. Radar system simulation method of economic, flexible and convenient, in the radar research field and engineering technology has been widely used.

This paper based on linear FM pulse radar, of radar simulation and processing. This paper mainly work is pided into three parts: linear FM continuous wave radar system is introduced, the radar echo simulation, the matlab software is introduced. First of all, introduced the LFMCW principle and method of the radar system is given, and the system frame. Then from radar target echo signal on the target simulation discussed the simulation method and process. After the software matlab simulation signal are introduced, and commissioning, finally, using the software simulation out the whole target echo simulation of the wave image, to the simulation results.

This paper presents a complete LFM radar system simulation and the treatment process, simulation of the radar signals, after radar signal processing and radar data processing, eventually form the correct waveform and display.

Key word: LFMCW radar target echo simulation

Title:The research of 8mm band short-range binding technology

Abstract:

Millimeter wave band is located between the infrared and microwave, except a common feature of the infrared and microwave, as well as its unique performance. With the guidance in the application of millimeter-wave radar, greatly improve the hit probability of precision-guided weapons and anti-jamming capability. Therefore, the study of the millimeter-wave short-range binding technology plays an important role in our military defense system.

Based on the millimeter-wave communication system, channel coding techniques. Paper mainly composed introduced is pided into three parts: the characteristics of the millimeter-wave communication system, the bookbinding art channel coding analysis, design a practical code to achieve the signal transmission and reception. First, the introduction of the characteristics and composition of the millimeter-wave communication system, the modulation and demodulation of the signal. And then to analyze the characteristics of the channel coding [7,4] Hamming code. Finally, the design of a practical code of signal transmission and reception, and its experimental Microcontroller C Programming Language verified. Given complete the communication with the encoding process of the millimeter wave binding techniques, the adopted encoding having a certain anti-jamming capability, allows for accurate decoding, the error rate is very low.
