A system theoretic approach to array processing
Demirkol, Aşkın; Demir, Zafer; Emre, Erol
In this paper, utilizing system theoretic concepts a sound, rigorous theory of array processing is established which leads to several new results. MUSIC, MIN-NORM, ESPRIT, and PISARENKO used for both spatial and temporal spectral decomposition of signals are well known techniques in array processing. In this work, a general approach generalizing them is presented. A theory for multipath case is provided for analysis and design of array structures without the assumption of linearity and equal spaceness which estimates the temporal frequency and the directions for coherent sources. Our approach is also developed to null signals in certain directions with certain frequencies, such as for multipath cancellation.

An ambiguity function aided target density function for radar imaging
Çınar, R. F.; Demirkol, A.; Demir, Z.
This paper investigates a new approach to target density functions for active sensor imaging. The data obtained from a phased array radar system is processed by the newly developed technique. In order to reconstruct the target density function, the ambiguity function -that is widely used as a radar performance tool- is employed. Theoretical background of the system model is examined and simulation results are achieved.
