    摘要:

    以系统输出信噪比为判据,建立了系统的作用距离R,最小可分辩温差MRTD,最小可探测温差MDTD与系统的噪声等效温差NETD和调制传递函数Hs之间的关系;并研究了这些性能参数的测量方法,为系统综合性能评估和性能测试提供了依据。

    Abstract:

    Taking the output signal to noise ratio ( SNR ) of systems as a criterion, the relationships among the detecting distance R , the noise equivalent temperature difference NETD , the minimal resolvable temperature difference MRTD , the minimal detectable temperature difference MDTD and the modulation transfer function of IR scanning detecting systems ( SDS ) were established. The testing methods for these figures of merit were also studied.As a result, the bases of the synthetic performance evaluation and the practical testing methods of IR SDS were provided.
