In the paper, prescale technology, interpolate method, averaging method and multiple period synchronization method are used to measure the frequency accurately. diode demodulating technology, and power attenuated method or probe coupling & water load technology are employed to measure the power of high power microwave. isothermal technology is used to improve the stability of demodulator and to expend the range of square linear region
本文採用預分頻法、內插法、多周期同步法、平均法實現了頻率的精確測量;利用二極體檢波技術，結合衰減法或探針耦合+水負載技術實現了大功率微波功率的測量;採用恆溫技術提高了二極體檢波器穩定度;完成了單片機串口通信協議設計和系統電磁兼容的分析和設計。 -
Phase modulation system is a superior system, can transmit data at high rate. in this thesis, digital fh - mpsk and fh - / 4dqpsk modulator and demodulator are given according to the frequency - hop communication characteristics. at last, we implement these systems in both hardware and software platform
本文根據跳頻傳輸的特點，對mpsk和4 - dqpsk這兩種相位調制方式進行分析，提出數字調制解調方案，並用matlab對其進行了模擬，最後還在ti公司的tms320c6416晶元上實現了這兩種系統。 -
The utilization of high speed dsp can highly increase the performance of anti - interference and anti - detection. the modulation mode, data rate and coding mode can be controlled by configuring the registers of modulator stel - 1109. the viewport and nco frequency control word selection can be accomplished by configuring the demodulator stel - 2105
Dsp通過i / o讀寫操作，控制調制晶元stel - 1109的讀寫寄存器，用來設置晶元的調制方式、數據速率、編碼方式等；而dsp對解調晶元stel - 2105讀寫寄存器的控制，則對解調的一系列視窗選擇及nco頻率控制字進行了設置。
