Impact of SAR impulse response function in interferometric measurement
2007 IEEE International Geoscience and Remote Sensing Symposium, 2007The stable point network (SPN) is a persistent scatterer interferometric technique developed by ALTAMIRA INFORMATION in 2001. The technique makes use of both ERS SAR and/or ASAR differential phase measurements to generate long term terrain movement and precise height maps with the same resolution as the original SAR images.

Errors involved in computing impulse response functions via frequency response functions
Mechanical Systems and Signal Processing, 1992Abstract This paper discusses the errors that are introduced when calculating the impulse response function from the frequency response function using DFT/FFT analysis technique. The impulse response function is used in many applications of system analysis where a description of the system characteristics is preferred in the time domain rather than ...

Volume 8: 27th Conference on Mechanical Vibration and Noise, 2015
Modal properties of a structure can be identified by experimental modal analysis (EMA). Discrete frequency response functions (FRFs) and impulse response functions (IRFs) between responses and excitation are bases for EMA. In calculation of a discrete FRF, discrete Fourier transform (DFT) is applied to both response and excitation data series, and a ...

Transformation function of the external ear in response to impulsive stimulation
The Journal of the Acoustical Society of America, 1974Impulse noise presents great difficulties in the estimation of auditory hazard. As a first step in determining the energy that actually reaches the cochlea during impulsive stimulation, the transformation function of the external ear was measured in response to impulsive stimulation. A model of the human external ear and live cat ears instrumented with
