One of the important parts of the infrared seeker is the counter countermeasure part. Seeking in a field of view with the existence of jammers is not simple and needs effective algorithms. In this paper, several methods of the detection in a crossed array trachers (CAT) seeker will be designed, simulated and evaluated. These methods depend on detecting the… (More)
We suggest a novel technique to measure the free spectral range of a Fabry-Perot etalon (FPE). The technique utilizes a Pound-Drever-Hall method using both reflected and transmitted lights of an FPE. We improve the measurement accuracy ~2 dB by using both of the lights.
We present flat-top microwave photonic filters through amplitude and phase shaping of optical frequency combs. Flat-topped filters with greater than 27-dB stopband loss are demonstrated using 32 taps with both positive and negative tap coefficients.
