The comprehensive target characteristics , target detection , discrimination requirements by using a micro- laser spectroscopic detection components , the use of optimized background suppression , target detection and anti-jamming signal processing a variety of advanced technology. This paper presents an application of the four-quadrant detector for laser fuze echo signal correlation detection method. Weak the laser fuze echo signal , interference , more difficult to handle , the farther the distance , the useful signal , the weaker.

In order to improve the detection of laser fuze distance , weak signal , digital signal processing is very important.

Commonly used method often interfere with the signal to determine a useful signal , thus affecting the ability of the laser fuze. Using wavelet transform and matched filtering coupled the laser fuze weak signal processing can extract useful signal from strong noise , and can effectively remove the strong interference signals. For scientific design and performance evaluation of laser detection system to provide effective guidance for laser proximity fuze target detection system for simulation modeling , analysis and the establishment of the the laser echo power and photoelectric conversion model , using the established model of the detection system simulation show that the model is feasible and effective.

The specific typical targets simulation can be inferred that the laser detection system can achieve the accurate identification of the target , and having a different shape of the target can be the difference of the echo waveform distinguish. The simulation tool of laser proximity fuze various effective performance analysis , and contribute to the laser fuze system performance improve and standardize.

Proximity fuze explained

Kajibei Firing pin actuation is initiated by the slider at the instant the detonator charge and the booster charge come into register. And based on the derived formula, the correlation between the maximal echo power and the incident height was given and simulated, which laer be helpful for the further researches of low altitude radio fuze. Please help improve this section by adding citations to reliable sources. Although proximal aortic surgery is less frequent than other cardiac surgery operations, this procedure itself is more challenging and technically demanding than other fuzw cardiac surgery techniques. Complications secondary to these injuries produce significant morbidity and include infection, nonunion, malunion, decubitus ulcers, fat emboli, deep venous thrombosis, pulmonary embolus, pneumonia, myocardial infarction, stroke, and death. By modifying the neutral gas profile in the accelerator, the plasma flow from the accelerator is maintained, driving the flow shear. Spatial versus Tree Representations of Proximity Data.

Proximity fuze

Zujar Two additional amplifiers detected and filtered this low frequency signal. Research and prototype work at Rheinmetall were halted in to devote available resources to projects deemed more necessary. If either is wrong, then even accurately aimed shells may explode harmlessly before reaching the target or after passing it. Various safety requirements are satisfied by a spring loaded slider operating in a channel transverse and adjacent to the booster charge. The feasibility of using optical technology to perform the mission of the proximity operations communications subsystem on Space Station Freedom was determined. A list of relevant references is presented. Dynamically variable spot size laser system.
