摘要在空间信息领域，人类的研究深度和广度不断加强和细化，随之而来就意着雷达系统的各项指标如探测距离、雷达分辨率、探测精度、最小发现距离等要有更进一步的提高发展。线性调频脉冲形式信号在此情况下应运而生，成为雷达领域的新兴热门。其信号形式具有大时宽带宽积的特性，能够发现和探测的目标距离更长，与此同时在接收端使用与之相对应的脉冲压缩法来获得窄脉冲信号，从而来提高距离分辨力。线性调频脉冲信号因而有效地解决了雷达分辨率和雷达探测距离不能兼得的矛盾。在系统设计过程中，这两个参数相对一般雷达系统都能够得到很好的改善和提高。

Title The analysis and simulation of
the linear frequency modulation pulse distance system
Abstract
In the field of information space, the depth and breadth of human studies continue to strengthen and refine, as a result,the indicators of the radar system like Detection range, the radar resolution, detection accuracy, the minimum distance found and so on need to have more improvment. Signals with the form of linear frequency modulation pulse get into our eyes and turns out to be a new and hot part in radar research. It has a large product of bandwidth and timewidth so that it can detect a further target in the same case.At the same time, it use the corresponding pulse compression method At the receiving end to obtain a narrow pulse signal, thereby to improve the range resolution. Chirp signal thus effectively solves the contradiction that resolution radar and radar detection range can not have both in the same time. In the process of system design, these two parameters -compared to a normal radar system-are able to improve and enhance very well.
In this artical,we combine the theoretical analysis and system simulation using the platform together.First of all,we search a lot of journals and materials,books which do help our research.And then we test and vetify the theroy by using the sofeware .
In this artical, we mainly study the linear frequency modulation pulse distance system.Including these parts：The Derivation of the Mathematical formulas of the transmitted signal and echo signal, Signal ambiguity function and also the feature of it, Simulation Study considering the Stationary and moving case and so on.Then, we do the design and simulation through the sofeware and vetify this theory
Keywords Signals with the form of linear frequency modulation pulse，Pulse compression technology，Signal processing．
