课程设计中首先采用Ising model的思想建立一个二维的模型,然后利用重要性抽样和Monte Carlo方法及其思想模拟铁磁-顺磁相变过程。计算了顺磁物质的能量平均值Ev、热容Cv、磁化强度M及磁化率X的值,进而研究Ev、Cv、M、X与温度T的变化关系并绘制成Ev-T图、Cv-T图、M-T图、X-T图,得出顺磁物质的内能随着温度的升高先增大而后趋于稳定值;热容Cv、磁化率X随着温度的升高先增大后减小;磁化强度M在转变温度Tc处迅速减小为零,找出铁磁相变的转变温度Tc大约为2.35(First of all, curriculum design idea of the Ising model used to establish a two-dimensional model, the importance of sampling and then use Monte Carlo simulation methods and their idea of ferromagnetic- paramagnetic phase transition process. Paramagnetic material calculated average energy Ev, heat capacity Cv, magnetization M and susceptibility X value, and then study Ev, Cv, M, X and temperature changes in the relationship between T and plotted into Ev-T map, Cv- T diagram, MT map, XT maps drawn paramagnetic material can be increased as the temperature increased and then stabilized value heat capacity Cv, magnetic susceptibility X as the temperature increases after the first minus small magnetization M in the transition temperature Tc decreases rapidly to zero Department to identify ferromagnetic phase transition around the transition temperature Tc for 2.35)

chirp
chirp信号产生比较
If you are aware of this and would still like to have a pseudo-chirp then you can take a look at the example below. I show the difference between trying to generate the type of chirp you are after and a real chirp signal. I also plot the derivative of the resulting signals, so I can highlight that between half cycles you will have a sometimes subtle (sometimes not so subtle) jump in gradient.

PCMTITEST2011
统一设定带宽、脉宽、采样率、脉冲重复频率,用Matab产生16个脉冲的LFM,每个脉冲有4个目标(低速,静止,高速,低速),第3个目标的距离、速度与学号有关。前3个目标的幅度相同,第四个目标幅度是前三个的一半。且距离与第2个静止目标相同。
依次做如下处理:
1 脉压
2 脉压后,相邻2脉冲做MTI(即相邻2个脉冲对应相减),产生15个脉冲
3 脉压后,16个脉冲到齐后,做MTD,输出16个多普勒通道
4 对MTD结果做CFAR(恒虚警)
(Unified set bandwidth, pulse width, sampling rate, pulse repetition frequency, and produces 16 pulses Matab LFM, with four goals each pulse (low-speed, static, high-speed, low speed), the first three goals of distance, speed and Student ID related. The first three goals of the same magnitude, and the fourth target range is half of the first three. And from the stationary target with the first two the same.
Followed by treatment as follows:
1 pulse
2 pulse pressure, the adjacent two pulses do MTI (that is adjacent to two pulses corresponding to the subtraction), resulting in 15 pulse
3 pulse pressure, 16 pulses in attendance after doing MTD, 16 Doppler channel output
4 MTD results do CFAR (CFAR))
