Compared with civilian code, P code has higher anti-interference and anti-deception, especially in the military field. However, due to the non-periodicity, high rate and large amount of data processing of P code, the improvement of acquisition speed and acquisition sensitivity is restricted. Based on the parallel frequency algorithm of matched filtering combined with fast Fourier transform (PMF-FFT), this paper designs an FFT module, which is configurable to a certain extent in FFT length and phase search parallelism. Combined with the design of time division multiplexing acquisition mode, it can achieve the flexible switching of multiple acquisition speeds and acquisition sensitivity. The test shows that the acquisition module has a variety of working modes in acquisition speed and sensitivity, is compatible with signal processing of a variety of symbol modulation modes, and is suitable for a variety of application scenarios.
