直扩码分多址DS-CDMA是利用高速的WALSH正交码序列作为地址码，与多用户信息数据相乘得到信息数据的直接扩频信号，再经过BPSK调制后发送出去，经过AWGN无线信道的传输后，在接收端与本地产生的地址码进行相关检测，从中将地址码与本地码一致的用户数据选出，把不一致的用户数据删除。(DS-CDMA DS-CDMA is the use of high-speed WALSH orthogonal code sequences as address code, with multi-user information data has been multiplied by the direct spread spectrum data information signal, and then after a BPSK modulated sent through AWGN channel after transmission, at the receiving end with the locally generated address code associated Detect, which will address code with local codes consistent user data elected to delete user data inconsistencies.)

本文首先研究了ISAR成像的基本原理，在理想转台模型的基础上对距离-多普勒(R-D)成像算法做了分析，对目前常用的运动补偿技术进行了对比和研究，并将这些技术用于雅克-42飞机的实测数据中。然后，论文系统地论述了压缩感知主体理论，重点对信号重构中的基追踪(BP)算法和正交匹配追踪(OMP)算法进行了深入的研究和讨论，并通过正弦信号的仿真结果验证了两种方法的有效性。(Firstly, the basic principle of ISAR imaging study, based on an ideal model for distance turntable- Doppler (RD) imaging algorithm to do the analysis of the motion compensation techniques currently used are compared and studied, and the use of these technologies in the measured data in the Yak-42 aircraft. Then, the paper systematically discusses the theory of compressed sensing body, focusing on the signal reconstruction of the base track (BP) algorithm and orthogonal matching pursuit (OMP) algorithm is conducted in-depth studies and discussions, and the simulation results verify the sinusoidal signal the effectiveness of the two methods.)

This circuit uses the AC6 block of SimPowerSystems™ library. It models a permanent magnet (PM) synchronous motor drive with a braking chopper for a 3HP motor. The PM synchronous motor is fed by a PWM voltage source inverter, which is built using a Universal Bridge Block. The speed control loop uses a PI regulator to produce the flux and torque references for the vector control block. The vector control block computes the three reference motor line currents corresponding to the flux and torque references and then feeds the motor with these currents using a three-phase current regulator.
