Description: 有两个程序一个是关于frft的源程序，一个是应用frft对线性调频信号进行检测的程序，原理是以变换阶数（不同的分数阶域）为变量对观测信号进行分数阶变换，形成信号能量在时频平面上的二维分布，在此平面上按阈值进行峰值点的二维搜索即可检测线性调频信号并估计其参数。-There are two procedures one on frft the source, one application frft linear FM signal detection process, the principle is to transform the order of (different fractional domain) as the independent variables on the observed fractional signal change, the formation of signal energy in two-dimensional time-frequency plane distribution in this plane, the peak threshold value by two-dimensional linear FM signal can be detected search and estimate its parameters.

Description: TEA5767的频率计算方法：
分频参数的计算公式为:
当HLSI位为1时
4*(fRF +fIF)
N=----------------
fREF
N = PLL内的频率合成参数
fRF = 要接收的电台频率
fIF = 中频= 225 kHz
fREF = 参考频率
晶振为32.768 kHz参考频率为 32.768 kHz
晶振为13M或6.5M时钟时参考频率为50 kHz
已知模块的晶振为32.768K
4*(fRF +fIF) 4000*((fRF/1k)K +225 K) 4000*((fRF/1k) +225 ) 1000*(fRF/1K +225)
N=----------------= ----------------------------------= ----------------------------=---------------------=(fRF+225K)/8192
32.768K 32768K 32768 8192
例如要接收87.5Mhz的频率，频率合成参数N=(87500000+225000)/8192=10708.6=10709.
往PLL寄存器写10709就能收到87.5M的频率。
同理知道PLL的参数也可以计算模块正在接受的频率，
fRF=8192*N-225K-void Get_Frequency(void)
{
unsigned char hlsi
unsigned int npll = 0
npll = Pll_Data
hlsi = radio_read_data[2]&0x10
if (hlsi)
Frequency_Data = (unsigned long)((float)(npll)*(float)REFERENCE_FREQ*(float)0.25-225) //频率单位:KHz
else
Frequency_Data = (unsigned long)((float)(npll)*(float)REFERENCE_FREQ*(float)0.25+225) //频率单位:KHz
}
