This invention discloses an orthogonal down-conversion method for digital intermediate frequency (IF) signals, primarily addressing the problem of high computational complexity in existing orthogonal digital down-conversion processing methods. The implementation involves decimation and mixing / filtering of the digital IF signal. Decimation occurs every three clock cycles, extracting one-quarter of the digital IF signal. Mixing / filtering involves multiplying the convolution coefficient sequence of a low-pass filter with the sine and cosine local oscillator signals generated by a numerically controlled oscillator (CNC) to obtain the convolution coefficient sequences of the I-path and Q-path filters. These sequences are then convolved with the decimated digital IF signal sequence and summed to obtain the I-path zero-IF signal and Q-path zero-IF signal, which are then transmitted to other signal processing modules in the FPAG system. This invention reduces the computational complexity of orthogonal down-conversion, lowers hardware resource consumption, and can be applied to general radar signal processing systems.
