WebJan 22, 2024 · As a demonstration, we consider a photonic crystal slab structure and show that differentiation operation with incoherent light can be achieved by subtracting the optical transfer function of the structure at two different frequencies. WebAtmospheric transmission throughout the electromagnetic spectrum is examined along with the range equation. Specific examples are presented for both incoherent detection systems (e.g., laser range finders and altimeters) and coherent detection systems (e.g., satellite trackers and clear air weather radars).

WebJul 6, 2024 · In coherent detection, a local carrier mixes with the received radio frequency (RF) signal to generate a product term. As a result, the received RF signal can be frequency translated and demodulated. When using coherent detection, we need to estimate the channel (frequency band).
