Incoherent demodulator matched filter

WebThe matched filter consists of a frequency-plane holographic filter, an achromatic-fringe interferometer, a color-compensating grating, and an achromatic doublet. The matched filter, a Fourier hologram, is made by recording the object spectrum and a collimated reference beam with an exposure wavelength λ 0. WebThe 3D matched filter is a powerful processing technique used to detect moving, weak & optical targets that are immersed in a noise field. This process uses the 3D processor to …
