    In this paper a new matrix-based method is proposed for. identification of radar pulse train. The proposed method, which is called NASH, can be used to identify the PRI for constant, staggered, and jittered signal. Previous matrix-based methods can only identify the first type of signal, i.e. constant PRI. The complexity of computation in NASH is approximately equal to 2.5N/sup 2/ which is lower t...

    We propose a design for a symmetric multi-output optical splitter which has a smooth transition between its input waveguide and its output waveguides. The design provides as many output waveguides as needed with no loss of the smooth transition. An example of this design having six output waveguides is provided and numerically investigated using the beam propagation method. View full abstract»
