摘　　要：针对火炮在靶场定型试验中需要检测回转半径尺寸的要求,提出了一种便于现场操作的基于测边网的火炮回转半径检测方法。在火炮检测现场布设测边网,采用条件平差的计算方法,建立条件方程式和法方程式,计算各边角的平差值,通过圆拟合得到火炮回转半径的尺寸。试验结果验证了该方法的可行性和有效性。Aimed at the requirement to inspect and measure size of the gun rotation radius dur-ing the qualification test in the firing range,a kind of method based on trilateration network was proposed to be easy and feasible for site operation.With the help of this method,firstly, the trilateration control network was established in the testing field;secondly,the condition adj ustment and normal equation were set up by use of the calculation method of condition ad-j ustment,and the adj ustment value of every side corner was acquired;finally,the rotation ra-dius value of the gun was obtained by use of the fitting circle.The test results inspect and veri-fy the feasibility and validity of the method.
