Coherent Change Detection for Multipass SAR
IEEE Transactions on Geoscience and Remote Sensing, 2018This paper focuses on the detection, from a stack of repeated-pass interferometric synthetic aperture radar (SAR) images, of such changes causing a target to completely lose the correlation between one epoch and another. This can be the consequence of human activities, such as construction, destruction, and agricultural activities, and also be the ...

Coherent or Heterodyne Detection
1978In the previous chapter we discussed the detection of the incident power in an optical or infrared wave, basically ignoring the actual frequency of the wave except in the value of the quantum energy and the wavelength or frequency cutoff of the photon detector.

Detecting coherent and incoherent frequency modulation
Hearing Research, 2000Three experiments investigated whether or not the auditory system contains a neural mechanism that is sensitive to differences in the pattern of frequency modulation imposed on widely separated carriers. Experiment 1 measured the discrimination between an unmodulated two-tone complex and one in which either coherent or incoherent frequency modulation ...

Detection efficiency of coherent optical radar
Applied Optics, 1984Using the Huygens-Fresnel principle, the detection efficiency of a coherent optical radar is formulated. This formulation includes the effect of misalignment between the signal field and the local oscillator field. In the far-field case, the detection efficiency of a diffuse target is approximately half that of a glint target when the transmitter and ...
