Incoherent detection
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). Publication: WebAbstract: In gravitational wave interferometric detection, the problem of stray light has received long-term attention. In the spaceborne gravitational wave detection program, the laser light emitted by the local interferometer produces backward coherent stray light when passing the telescope while the radiation from space that is incident to the spacecraft …

WebMar 1, 2024 · Optical receivers can be broadly classified into 5 types depending the type of detection signal: Incoherent or direct detection (for amplitude modulated signals) Self-coherent or differential coherent detection (for differential amplitude modulated signals) Coherent detection (for complex signals) Direct detection (for complex signals) WebHowever, when fast hopping is used, the fact that phase coherence cannot be maintained across hops means that the energy from the successive hops in one symbol must be combined incoherently; this causes a non-coherent combining loss. FHSS signals are primarily used in AJ and CDMA systems.
