[Other] DSP_RADAR-

Description: 在DSP环境下编程实现对回波信号的脉压，MTI和MTD处理。 MATLAB程序内容：提供了脉压，MTI，MTD的实现方法，同时生成数据文件以供DSP程序中使用。流程说明：做脉压处理时，导入DSP的回波数据应为时域数据，脉压系数为频域数据。这些数据是在MATLAB程序中生成的。在DSP中，对回波数据进行FFT处理将其变换到频域后，将其与频域系数进行点积，对点乘结果再做一次逆FFT，将频域结果转换到时域，在这一步中需要调用函数fft_flp32.asm，其功能是实现输入数据的FFT变换。这里要求同学们利用FFT程序实现IFFT的功能。具体方法请大家自己查找。这个库函数的入口参数包括（输入数据，缓存区1，缓存区2，输出结果）(说明：原库函数中的入口参数比是6个而不是现在的四个，为了方便同学们调用，所以库函数调用的时候稍做了修改，希望你们以后再调库函数的时候注意)。所谓缓存就是在程序中再开辟一个存储空间，和输入数据的大小一样。所需的程序和旋转因子表都和这个文档放在同一个文件夹内了。在做MTD的时候调用的函数是fft_16.asm。 -DSP programming environment in the echo signal pulse pressure, MTI and MTD processing
