摘要: 針對(duì)雙重頻解速度模糊系統(tǒng)中，信號(hào)參數(shù)選擇不合理導(dǎo)致解速度模糊存在量化誤差的問(wèn)題，推導(dǎo)了雙重頻解速度模糊的量化要求。為了增大最大不模糊速度，該文提出多層解模糊系統(tǒng)，提出了一種四重頻脈沖串解速度模糊的模型，推導(dǎo)了四重頻信號(hào)脈沖個(gè)數(shù)的下界，并簡(jiǎn)化為了三重頻脈沖串信號(hào)模型。仿真驗(yàn)證了理論推導(dǎo)的正確性。Abstract: In dual pulse repetition frequencies radar systems, mathematical deduction of the number of pulse repetition intervals required to satisfy quantitative requirements is presented to resolve velocity ambiguity. Multiple layer systems to increase the maximum unambiguous velocity are proposed. A new model of quadruple pulse repetition frequencies signal is proposed. The lower bound of the number of pulse repetition intervals required to satisfy quantitative requirements is deduced and quadruple pulse repetition frequencies signal is simplified as triplet pulse repetition frequencies signal. Simulation results validate the accuracy of our deduction.
