Abstract: A new method for refraction tomography is provided that uses differential delay times. Different types of refracted waves including head waves and diving waves are inverted. First, traveltime/offset functions for station in the seismic survey are estimated from first-arrival picks. Next, the traveltime/offset functions are transformed into velocity/depth functions to make up a near-surface model. Then, long-period statics are calculated using the derived near-surface model. Finally, short-period statics are estimated by a surface-consistent decomposition of the traveltime residuals.

Patent CA-2330430-A1 (CA)
Inventor: YAMADA YUKINORI
IPC: G01S7/28
Filed: 1999-03-24
Abstract: This FM-CW radar apparatus comprises a transmitter section, a receiver section, and a signal processing section. The transmitter section transmits a frequency-modulated continuous wave as a transmitted wave. The receiver section receives a radio wave resulting from reflection of the transmitted wave at a target, as a received wave, by a receiving antenna comprising an array of antenna elements, generates a beat signal which is a difference of the transmitted wave and the received wave in each of channels of the respective antenna elements, and converts this beat signal to a digital beat signal by A/D conversion. The signal processing section executes a digital beamforming operation with the digital beat signals and detects the target from the result of the operation.      The receiver section has a switch means for selectively connecting either one of the antenna elements to a circuit for generating the beat signal, and this switch means connects only part of the antenna elements to the beat signal generating circuit in one period of the repetition periods of the frequency modulation.
