A Study on Accurate Ranging Method of a Dual-Wavelength Orthogonal FMCW Laser Fuze in a Complex Aerosol Environment

A laser fuze model employing orthogonal frequency-modulated continuous wave (FMCW) technology is developed, incorporating wavelengths of 405 and 1550 nm. The present investigation focuses on scrutinizing the transmission properties of four prevalent aerosol categories, namely dust, water-soluble particles, marine particles, and soot. To facilitate target identification and distance estimation, an algorithm is introduced, leveraging the analysis of frequency spectrum data derived from beat signals. The simulation outcomes substantiate the model’s proficiency in effectively discerning targets and precisely ascertaining their range, even when confronted with aerosol interference.
