A wide-aperture optical correlator-spectrum analyzer has been developed that achieves its full theoretical maximum processing gain of 36 dB. This 4000-channel system is coherent across the 100-mm-diam aperture with 100-lines/mm resolution at the center. The system noise is not perceptible, and the time-bandwidth product is 9000. Performance tests are described and evaluated for aperture coherence, Fourier transform accuracy and resolution, and processing gain.
一种宽孔径光学相关器-频谱分析仪已经研制成功，其实现了36分贝的全理论最大处理增益。这个4000通道系统在直径100毫米的孔径上具有相干性，在中心处分辨率为每毫米100线。系统噪声不可察觉，时间带宽积为9000。描述并评估了该系统在孔径相干性、傅里叶变换精度和分辨率以及处理增益方面的性能测试。
