利用接收电视信号的多站系统进行目标定位以克服距离模糊

较短的不模糊距离是以电视信号为辐射源的双基地探测系统所面临的难题之一,本文深入研究了利用测量距离和的目标定位方法克服距离模糊的机理,提出了根据发射源的最大辐射距离,来确定最大不模糊可测椭球面的最优方法,指出了基线距离与最大不模糊可测空域的变化关系,对充分发挥辐射源的威力和选择最大不模糊可测空域提出了一条有效的途径.

LOCATING TARGETS USING MULTISTATION RECEIVER SYSTEMS IN OVERCOMING THE RANGE AMBIGUITY OF TELEVISION SIGNALS

Poor unambiguous range is considered one of the problems the television based bistatic radar is faced with. In this paper, the mechanism using target locating to overcome range ambiguity was studied extensively, where it is the sum of transmitter to target and target to receiver range that is measured and a kind of optimal method was proposed to determine the maximum unambiguous and measurable ellipsoid according to the extreme operating range of the transmitter. The relation between the baseline and maximal unambiguous and measurable airspace was pointed out. This will offer an effective approach for utilizing fully the power of the transmitter and selecting the maximum unambiguous and measurable airspace.
