文章是在我所研制的两种雷达信标的基础上写出的。作者着重探讨了信标的作用距离和扫频方式。用实验数据证实了雷达信标的作用距离与发射功率之间的理论关系,即作用距离与发射功率的平方根成正比,从而提出了一种在实验室条件下确定雷达信标最大作用距离的方法。利用此法,只要知道衰减器的读数和试验点离实验室的距离,就可计算出雷达信标的最大作用距离。海上试验结果证明上述方法是正确的。在扫频方式方面,作者提出了一种可移阶梯式扫频方案,把快扫和慢扫的优点结合在一起,收到了较好的显示效果。
The article was written on the basis of two radar beacons I developed. The author focuses on the beacon distance and frequency sweep method. The experimental data confirm the theoretical relationship between the range and transmit power of the radar beacon, that is, the range is proportional to the square root of the transmit power. Therefore, a method to determine the maximum range of radar beacon under laboratory conditions is proposed. With this method, the maximum distance of the radar beacon can be calculated by knowing the attenuator reading and the distance of the test point from the laboratory. The sea test results prove that the above method is correct. In terms of the way of frequency sweep, the author proposed a kind of movable step sweep scheme, which combined the advantages of fast sweep and slow sweep, and received a good display effect.
