Abstract:

The concept of transcoherence function maximization for antenna system optimization is demonstrated by means of examples. These include the optimization of planar apertures subjected to both random and nonrandom fields from single and multiple point-sources the determination of the optimum spacing of elements in a direction-finding interferometer array located in a random medium the space-time optimization of a linear radar and the optimization of systems in the presence of stationary random media. Finally, the optimization technique is applied to the problem of an antenna embedded in a nonstationary medium, such as the hot plasma that would surround a space vehicle antenna during the reentry phase. The amplitude and phase shading of such an array are the variable parameters chosen for optimization of the system, and medium effects, background object noise, receiver noise, etc. are considered.
