QPSK
Direct sequence spread spectrum (DSSS) communication systems has been widely
used in these years for its advantage of wide spectrum, low working Signal-to-Noise
ratio (SNR), anti-interference, anti-multipath effect and capability of LPI and LPD.
They are increasingly replacing conventional communication forms and obtaining
extensively applications in modern military and commercial communication systems,
for example, CDMA communication system, GPS , measuring and control system,
satellite chain, identification of friend or foe and etc. Therefore, corresponding DSSS
electronic counter technique becomes a big problem to solve in electronic warfare
domain. DSSS electronic counter technique including blind detection, blind parameter
estimation and spreading sequences estimation. For the issue of DSSS electronic
counter technique of DSSS/QPSK signal damaged by strong additive white Gaussian
noise (AWGN), the main research content in this dissertation as follow.

TargetLocatAccuracyRadarNetwork
分析了影响多雷达组网对目标跟踪精度的因素以及与单雷达的差异,提出了定义雷达网目
标定位精度,以及评估多雷达组网后在目标定位精度方面带来增益的方法。推导了雷达网对目标定
位精度和相应评估指标的估计公式。该文方法不要大量的计算机仿真就可以方便地评估2-D、3-
D以及混合雷达网的目标定位精度和效能。通过应用实例说明了该文方法的优点和有效性。
(The factors that affect the location accuracy of target tracked by multi-radar are analyzed.The method
to define target location accuracy and the metrics to evaluate the accuracy improvement efficiency of a radar net-
work are presented.The analytical expressions are developed to estimate the target location accuracy and the effi-
ciency metricsof a radar network.The presented method is convenient to evaluate the target location accuracy and
the efficiency of 2-D,3-D as well as the heterogeneous radar network instead of the tedious computer simula-
tions.The advantages and the validity of the method are demonstrated by an application.

频率估计
1）产生一个单频实信号，加上一定信噪比的噪声。
2）对含噪声的信号进行频率估计。估计方法可以查阅相关文献。
3）统计估计出来的频率和真实频率之间的误差。
4）验证该频率估计算法在不同信噪比、不同数据长度下、不同频率时候的性能。
(Frequency estimation 1) produce a single-frequency real signal, plus a certain SNR noise. 2) noisy signal frequency estimates. Estimation method can access relevant literature. 3) out of the statistical estimation and frequency error between the true frequency. 4) Verify that the frequency estimation algorithm under different SNR, different data length, when the frequency of different properties.)
