When conformal antennas array perform angle measurement based on the approach of conventional adaptive monopulse,the curve of monopulse ratio may be seriously distorted if there is mainlobe jamming . Consequently,the precision of the angle measurement is poor .In this paper,we propose a method of adaptive monopulse angle measurement for conformal antennas array .The conventional adaptive sum beam is formed first.Then monopulse ratio restraint is posed,and the adaptive difference beam is formed .Finally,the outputs of the sum beam and difference beam are used to measure the angle .Simulation demonstrated that the proposed method can suppress the mainlobe jamming and guarantee good measurement precision of azimuth and evaluation angles .% 针对主瓣干扰背景下，当共形阵采用常规自适应单脉冲方法测角时，其单脉冲比曲线严重失真，导致测角精度严重下降的问题，提出了一种基于共形阵的自适应单脉冲测角方法。该方法首先对阵列进行常规自适应和波束形成，得到阵列和波束输出；然后通过施加单脉冲比约束求取自适应差波束权矢量，从而形成阵列差波束输出；最后利用输出的和、差波束实现测角。仿真结果表明，和常规方法相比，该方法能在抑制主瓣干扰的同时，较好地保证共形阵对目标方位角、俯仰角的测角精度。
