The invention discloses a real-time high-precision monitoring method for an instrument landing system. The real-time high-precision monitoring method comprises the following steps: a monitor receives an emission signal and a space synthesis signal of the instrument landing system in real time and carries out high-speed signal sampling on the emission signal and the space synthesis signal; under the condition that the signal sampling rate is not changed, multi-dimensional parallel processing is carried out on the sampling signals, and multi-dimensional parallel synchronous high-speed sampling signals after speed reduction are obtained; the full-low-speed multi-dimensional parallel NCO module outputs orthogonal local oscillator signals with different frequencies by adjusting the phase increment in real time; performing multi-dimensional parallel orthogonal down-conversion processing on the multi-dimensional parallel high-speed sampling signal and the multi-dimensional parallel high-speed orthogonal local oscillator signal to generate a multi-dimensional parallel low-speed orthogonal signal of the high-speed sampling signal; and performing full-speed-reduction multi-dimensional parallel FIR filtering processing on the multi-dimensional parallel low-speed orthogonal signal, and outputting a full-low-speed processing result of the high-speed sampling signal. According to the invention, the number of processing stages and processing delay links are reduced, and high sampling rate, high precision and high real-time performance of monitor signal processing are ensured.
