Diagonal Padé approximation (i.e. the order of numerator and denominator polynomials is equal) is selected to balance the approximation accuracy and computational complexity; the Padé coefficients are stored as a lookup table (LUT) to avoid real-time repeated calculation. Although the pre-calculated spectrum requires a large storage space (such as 1KB order per spectrum), it can significantly improve the subsequent analysis efficiency; within 0.05 cm -1 from the center of the spectrum, high-precision numerical integration or fast algorithm (fast Fourier transform combined with iterative optimization) is directly used to process the main peak and adjacent area to ensure the resolution of the core spectrum; double-precision floating-point operation is used for the main peak, and the pre-calculated Padé approximation coefficients are called for the tail region to realize seamless connection through interpolation or extrapolation.

[0049] The power is dynamically adjusted using a PID algorithm or fuzzy logic.

[0050] Specifically, the radiation transmission model approximates the line tail attenuation characteristics by the distribution of poles and zeros in the line tail region of the infrared spectrum to obtain approximation coefficients; in the center of the infrared spectrum, the main peak and the adjacent region are processed by fast Fourier transform combined with iterative optimization to obtain accurate coefficients; the approximation coefficients and the accurate coefficients are smoothly transitioned by interpolation in the center of the spectrum and the line tail region to obtain the transmittance curve of the entire infrared spectrum.

[0060] The interference cancellation technology is used to perform band-pass filtering on the superimposed signal (center frequency 38kHz, bandwidth ±5kHz) to eliminate the interference of environmental infrared noise.

[0061] The layered decoding architecture uses a three-stage layered processing model:

[0062] Physical layer decoding: Verify data integrity through CRC-16 check (the check range covers the weapon protocol version number to the check code field);

[0063] Logical layer analysis: Extract weapon identification codes, compare preset weapon library parameters, and apply dynamic weighting algorithms when analyzing damage values:

[0066] ,in, The multiple regression model constructed by visibility V and water vapor W is used to calculate L path is the path loss value, L sys is the inherent loss value of the system, d is the distance between the transmitter and the receiver, and λ is the wavelength of infrared light;

[0067] Based on the hierarchical decoding results, a fuzzy PID controller is used to adjust the transmit power:
