At first the merits and implementation of the digital pulse compression subsystem are introduced in this paper. then the characteristics of phase coded signals are discussed and the two classic binary phase codes ? ? barker code and m - sequence are dealt with in details in the following
文中首先綜述了數字脈沖壓縮的優點及其實現方法，接著討論了相位編碼信號的特點，並詳細分析了巴克碼和m序列這兩類典型的二相碼信號。 -
In the fourth chapter, firstly, the fsk / psk signal function is presented, then, the signal which frequency and phase are modulated by costas code and barker code for each are analyzed at the same time. after that, the target returns and clutter returns are analyzed and modeled. at last, both of the time correlation characteristics and space correlation characteristics are theoretically analyzed
在第四章中，首先給出fsk / psk信號的表達式，並對一種分別採用costas碼和barker碼進行頻率和相位調制的fsk / psk信號進行分析，然後對fsk / psk信號的目標回波和雜亂回波進行分析與建模，接著，對雜波信號的時間相關性和空間相關性進行理論分析，由分析結果可知， fsk / psk雷達雜波的時間相關性不變、空間相關性增強。 -
Through a lot of experiments and simulations, analyzing the uwb channel model, studying on many papers, a new synchronization algorithm based on barker code and a new channel estimation method based on music algorithm are given. the simulation results of synchronization algorithm in which uwb channel model is used are gotten, and the channel estimation algorithm is demonstrated by measurement data. anyway, both of them get good conclusions
