Efficient multipath searching to improve acquisition probability in TDD-CDMA;

Granular Computing Based Hierarchical Concept Capture Algorithm in Multi-Valued Information System

Then,according to the characteristics of the forth generation short range air-to-air missile,give several typical target maneuver model and get out the target maneuver region with random start-time and a seeker acquisition probability arithmetic.

Aiming at the diversification of function system and homing modes in the development of submarine-launched torpedo,this paper analyses the advantages in operational application of wake homing torpedo based on its mechanism,such as stronger counter-countermeasure,higher speed,and higher target acquisition probability for selected target.

Under a certain satellite and acquisition probability,the total scan field of the acquisition system will be the minimum during the foundation of links if the scan fields of the single scan of two terminals are equal.

According to the reception principles of GPS receiver, the acquisition probability of GPS receiver to repeater deception jamming is derived in this article, and the probability curves of GPS receiver receiving repeater deception jamming as well as GPS satellite signal is obtained by simulation.

Deduce the FB formula for TSM, combined with the idiographic rule, a kind of mathematical model for capture probability is established, and the relationship between capture probability and scan parameter is analyzed, including the low speed scan and the high speed scan.

The simulation results show that this method has the feature of short synchronization time,high capture probability,low false probability and high anti-jamming performance.
