集中质量音叉式引力波天线与Vela星引力辐射探测的探讨

本文提出并计算了一种接收Vela星引力辐射的集中质量音叉式机械谐振型低频天线。指出,由于Vela星引力波信号的连续性和单色性,可以采用信号积累方法提高接收灵敏度。最后给出了灵敏度可以达到目前理论估计的Vela星引力辐射强度的天线参数。此种天线也适用于其他低频引力波探测。 关键词：

DESIGN OF A TUNING FORK ANTENNA WITH COLLECTIVE MASS FOR DETECTING GRAVITATIONAL RADIATION FROM VELA PULSAR

In this paper, we advanced and designed a mechanical resonant antenna, which is a tuning fork with collective mass, for detecting gravitational radiation from Vela pulsar. And showed that the sensitivity of antenna can be increased by the method of accumulation signal because the gravitational radiation signal from Vela pulsar is a continuous and monochromatic signal. Last, the parameters of antenna are given, the sensitivity of which can come up to gravitational radiation intensity from Vela pulsar which is estimated by the present theory.
