“…In addition, the coupler architecture makes possible for the optical signals to interact with each other. A last solution is proposed in [34]. It consists in using an optical concentrator to bring all the signals in front of a single photodiode, while keeping them physically separated from each other, in order to add and convert them at the same time.…”

In the fields of radar imaging and detection, the use of optical components appears as an attractive solution to overcome limitations of current technologies. This paper focuses on the development of a new class of microwave-photonic radar imaging systems enabling volumetric image reconstruction. These operations are made possible using a multiple-input multiple-output antenna array architecture combined with the conception of a dedicated optical multiplexing technology to limit the complexity of the whole reception chain. Particular emphasis is placed on the development of mathematical formalisms specifically adapted to these microwave-photonic radar architectures, making it possible to model the measurements carried out and to reconstruct three-dimensional radar images. These solutions are validated by the reconstruction of complex scenes with a multiple-input multiple-output radar made of up to 16 transmitters and 16 receivers.

Monte-Carlo simulations of optical speckle noise are performed to predict the range of gain fluctuations for photonic devices which multiplex many single-moded inputs into single multimode waveguides. Here, two waveguides are simulated which bound the cases of interest: a few mode fiber and a standard multimode fiber. When fully-excited and after spatial-filtering by a 10µm photodiode, the former’s gain variations can range up to the mean value of the gain itself, ΔG ≈ 〈G〉, whereas for the latter, ΔG ≈ 3.4〈G〉. In certain cases, ΔG can be reduced by offsetting the photodiode relative to the waveguide, results which cannot be predicted using standard analytical speckle noise theories.
