22906 针对具有已知扫描周期特性的辐射源无源定位问题，该文提出一种基于主瓣到达角(DOA)和扫描截获时间差(TDOI)的联合定位体制。 The determination of the scanning emitter position with known scan rate using Direction Of Arrival (DOA) and Time Difference Of Interception (TDOI) is investigated.
22907 通过对其定位误差的克拉美-罗下限(CRLB)推导，给出了联合定位体制的性能与DOA 和信号截获时间(TOI)观测量的等效测角噪声功率比的关系。 The Cramér-Rao Lower Bound (CRLB) of the DOA and TDOI based localization regime is firstly derived. It demonstrates that the equivalent DOA measurements noise power ratio of the individual regime is closely related to the improvement of the combination regime.
22908 为了利用非线性联合观测量确定扫描辐射源的位置，通过将 TDOI 观测量转换成等效 DOA 观测量，给出一种加权伪线性最小二乘(WPLS)定位方法； To exclusively determine the position of the scanning emitter, the TOI measurements are transformed to the corresponding DOA measurements and then a Weighted Pseudo-linear Least Square (WPLS) estimator is proposed.
22909 为消除观测矩阵相关噪声导致的 WPLS 估计偏差，提出了一种加权辅助变量(WIV)定位方法，算法复杂度约为 WPLS 算法的 2 倍。 However, the WPLS is biased due to the noise correlation between the regressor and regressand of the pseudo-linear equation. The Instrumental Variable (IV) method is resorted to eliminate the bias caused by the WPLS, and a Weighted IV (WIV) estimator, at the cost of two times computational complexity of the WPLS, is proposed.
22910 仿真结果表明，WIV 方法的定位误差在辐射源单个扫描周期内即可达到 CRLB，定位性能与极大似然(ML)定位方法相当；随着观测次数的增多，WIV 方法可以渐近达到无偏估计。 Simulations show that the WIV performs approximately to the Maximum Likelihood (ML) estimator. It can reach the CRLB in one scan cycle, and is asymptotic unbiased within multiple cycles.

22912 为了增大最大不模糊速度，该文提出多层解模糊系统，提出了一种四重频脉冲串解速度模糊的模型，推导了四重频信号脉冲个数的下界，并简化为了三重频脉冲串信号模型。 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.
