Abstract

Abstract:

Focusing on the detection of the low-altitude target, the distributed network detection system is proposed which adopts the methods of the base station transmission, distributed reception, time of arrival (TOA) location and network detection, and uses the layered tracking and trajectory management to effectively reduce the false trajectory. The system is suitable to the detection of the low-altitude target. It is suggested to use the parameters of the distributed extensibility and low-altitude coverage to assess the system. The simulation result under square and hexagon deployments verifies the detection ability of coverage and accuracy of the system. Compared with traditional monostatic radars, it has fine low-altitude detection and expansion capability.

Key words: low-altitude target, distributed, radar network, distributed extensibility coefficient, low-altitude coverage coefficient
