The theory of soplat using frequency rate is discussed in chapter 2. based on this theory, this chapter studies the observed discrete - time signal. the crlb of continuous wave and coherent pulses frequency estimation are also studied
論文第二章討論了利用頻率變化率的單站無源定位原理，在此基礎上，介紹了單站無源系統中接收信號的模型，並分析基於各模型的頻率估計的cramer - rao下界。 -
A new method for doa estimation in certain nonstationary environments is presented in chapter 4. the maximum likelihood ( ml ) estimations of doa ' s of multiple rapidly moving sources is derived and the theoretical variance of angle estimation and the corresponding cramer - rao lower bound ( crlb ) are also given. its simulations show that this parametric technique is able to resolve closely spaced sources
提出了一種非平穩環境下的最大似然doa估計方法，該演算法適合於時變doa的情形，並分析了其參數估計性能，給出了角度估計的漸進方差的解析表達式，表明了常規的最大似然doa估計是本文的一特殊情形。
