Compared with no-game and maxmin strategies, the radardetection probability of Nash equilibrium strategy can be increased by 12.02% and 3.82%, respectively. It isproved that the Nash equilibrium strategy of this paper is closer to the Pareto optimality.
19326 短脉冲非相参雷达(NCSP)的辐射源输出微波脉冲持续时间短，针对于高速运动目标而言，其脉冲持续时间内的目标运动可忽略不计，对回波信号不需进行专门的脉冲内运动补偿。 The microwave source of Non-Coherent Short Pulse (NCSP) radar transmits short pulse. Thus, for high velocity targets, the motion effect in the pulse duration can be neglected, and the echo signal does not need special motion compensation.
19327 为了利用短脉冲非相参雷达信号进行逆合成孔径雷达成像，该文应用补偿相参处理的方法，去除辐射信号包络时间不确定性和初始相位的不确定性影响， In order to use the NCSP radar signal for Inverse Synthetic Aperture Radar(ISAR) imaging, the compensation coherent processing method is applied to removing the uncertainty of the envelope time and the initial phase uncertainty.
19328 在常规方法进行包络对齐和初相补偿后可利用距离-多普勒(RD)方法进行逆合成孔径雷达成像，仿真验证了补偿后信号成像的可行性。 Assuming that the echo is envelope-aligned and initially compensated by conventional methods, ISAR radar imaging can be performed using the Range-Doppler (RD)method, subsequently. The simulation verifies the feasibility of the compensation signal ISAR imaging.
19329 然而，短脉冲非相参雷达的载频随机抖动的因素会导致距离-多普勒成像结果在多普勒维度产生随机调制的旁瓣，影响成像的质量。 However, the carrier-frequency random jitter factor of NCSP radar causes random-modulated sidelobes in theDoppler dimension, which affect imaging quality.
19330 利用稀疏恢复技术，在成像空间中对目标的散射中心进行稀疏重构，利用正交匹配追踪(OMP)算法和稀疏贝叶斯学习(SBL)算法进行成像，从而实现了抑制非相参因素引起的成像旁瓣，改进了成像质量，通过仿真验证了方法可行性。 In this paper, the sparse recovery technique is used to performsparse reconstruction of the target scattering center in the imaging space. The Orthogonal Matching Pursuit(OMP) algorithm and the Sparse Bayesian Learning (SBL) algorithm are used as the recovery algorithm forimaging simulation experiments. The simulation results show that the sparse recovery technique can suppress the imaging sidelobes caused by non-coherence and improve the imaging quality.

19332 该滤波器芯片采用绝缘体上硅材料(SOI)，利用有限冲击响应原理，通过调节各支路上的热光调制器，可以实现带宽可调、形状因子大于0.55的滤波曲线，以及中心频率可调、带宽可调和滤波形状可变3种不同滤波功能。 This filter is based onSilicon-On-Insulator (SOI) and an eight-tap finite impulse response. By controlling the thermal heaters on theamplitude modulator and phase modulator of each tap, a rectangular filter with tunable bandwidth and highshape-factor greater than 0.55 is obtained. Furthermore, the tunability of central frequency, bandwidth andvariable pass-band shape can be also realized.
19333 该滤波器尺寸小、重量轻、灵活性高，能适用于大带宽信号处理，并能提供一种理想的信道划分方式，可广泛应用于国防领域和5G网络中。 Small size, light weight and flexibility are advantages of the preposed filters, moreover, it can be applied to large bandwidth signal processing and an alternative method to part the channels. So it can be widely used in defense field and 5G networks.
