摘　　要：为了对小样本下机载火控雷达探测距离指标作出合理验证,节约试验成本,通过分析常用雷达探测距离评定方法不足的基础上,从工程实际出发,提出了用Bayes小样本理论可以有效地融合定型试验前的信息,结合少量的定型试验样本就可以对雷达探测距离作出比较客观评价,并根据机载火控雷达探测距离试验的实际特点,给出了小样本情况下的雷达探测距离评估方法。To make a reasonable distance index verification under small samples of airborne fire control radar with lower test cost,through analyzing the common radar detection distance evaluation method on the deficiency from the engineering practice,Bayes small sample theory is put forward to effectively fuse the information before type approval test. The radar detection distance can be objectively evaluated by combining a small number of type test samples. According to the actual characteristics of airborne fire control radar range test and evaluation method of distance detection under the condition of small samples of radar are presented.
