我们计算了斯普林希尔（渥太华）和基督城（新西兰）雷达的响应函数。利用我们之前的研究（Jones 和 Brown，1993）中发现的六个零星射电流星源的大小和位置，我们确定了每个雷达对每个源的响应。然后，使用最小二乘法拟合几年来收集的数据，我们确定了每个来源的强度。对初始列车半径进行校正后，总通量与非雷达数据非常一致。两个雷达的结果显示出两者可见源的良好一致性。对于个别年份，拟合度在 5% 到 10% 之间，但每年之间确实存在一些变化，这可能是由于大气影响。
We have calculated the response functions for the Springhill (Ottawa) and Christchurch (New Zealand) radars. Using the sizes and locations of each of the six sporadic radio-meteor sources found in our previous study (Jones and Brown, 1993), we have determined the response of each radar to each of the sources. Then, using least-squares fit to data collected over several years, we have determined the strength of each source. Excellent agreement with the non-radar data is obtained for the total flux after application of a correction for the initial train radius. The results from the two radars show good consistency for the sources which are visible to both of them. For individual years the fits are good to between 5 and 10% but there does appear to be some variability from year to year which may be due to atmospheric effects.
