雷达测量精度雷达测量正确性或误差大小的量度。测量误差，一般用测量值与真实值之差的平方的统计期望值（均方误差）或平方根（均方根误差）来表示。雷达所测量的目标参数通常包括目标距离(回波时延)、距离变化率（多普勒频移）、方位角和俯仰角（回波到达角）等。现代雷达还能测量目标尺寸、形状和其他参数。测量精度的根本限制因素是噪声。根据参量估计理论可以求出雷达测量的极限精度，并把它作为设计和评价雷达的重要依据之一。雷达回波由信号s(t-T)加噪声n(t)组成，式中T是回波信号的时延。时延T的估计值的均方根误差的下限为 式中分别为信号能量和有效带宽;N0为噪声的功率谱密度(即单位带宽内的噪声功率)；s(f)为s(t)的傅里叶变换。多普勒频移的估计值的均方根误差的下限为式中为信号的有效时宽。对于任意波形总有。因此这说明,只要有足够大的信噪比E/N0并选择βα足够大的雷达信号，测量时延（距离）和频移（速度）均可获得所希望的精确程度。由于天线方向图G(θ)和天线口径面上场的幅度分布A(x)之间也近似有傅里叶变换的关系，可以同样求得角度估值的均方根误差的下限为式中γ称为有效口径宽度；λ为雷达波长。因此，雷达测量精度与雷达波形有密切关系。
