摘要:
A FOV(field of view) dependent LOS(line of sight) scan method and apparatus for a turret aided camera system with continuous zoom optics is disclosed. According to this invention, the scan width and rate of the LOS are automatically determined as a function of the FOV selected by the user: scan width = f1(FOV, m) and scan rate = f2(FOV, te) where m is the observation range constant and te is the eye integration time. Moreover, the sensitivity to the FOV can be controlled by adjusting the relevant parameter sets (said m and te), allowing the user to select the scan condition proper to himself. This invention is quite useful for all kinds of turret aided camera system (the IR or day light TV cameras) for reconnoitering application.

Provided are shock waveform synthesis methods for a shock response spectrum over a short time interval, which are used for a shock response spectrum test. For the purpose, the shock response spectrum test is performed by including the steps of: obtaining each time τ k ( k = 1,2,···, M ) at which a maximax value is detected in the response history due to a zero delay wavelet input, wherein a natural frequency of the SDOF system with a Q (quality factor) of 10 equals to the wavelet frequency of the zero delay wavelet input; and establishing each delay time δ k as δ k = τ 1 - τ k ( k = 1,2, ···, M ).

Disclosed is an active sonar system capable of estimating a direction and a range of a target by using a sound pulse. A target range error can be estimated by the active sonar system, by comparing a range determined by applying a multipath eigenray model based on underwater environmental data to a range calculated by multiplying a 1-way target detection time by a reference sound velocity.
