Multi-function phased array radars (MFPARs) are capable of executing several tasks without any rotating antenna by jointly optimizing limited time and energy resources. The allocation of radar time resources is usually referred to as scheduling in radar resource management (RRM) literature. In this thesis, two scheduling algorithms, namely multi-type adaptive time-balance scheduler (MTATBS) and knapsack scheduler (KS), are proposed for real-time operations. A resource-aided technique called as the multi-frequency band usage is developed to increase the applicability of task interleaving. A simulator for MFPAR system is implemented to apply RRM techniques with different optional choices, such as adaptive update-rate, dynamic task prioritization, tracking, task interleaving. The simulator is designed in a way that each of the blocks can be individually modified according to RRM constraints. Target selection problem emerges when there are more than one target concurrently requesting track update. It is suggested to adopt the solution methods for the well-known machine replacement problem to the problem of target selection and track update is solved with the method of decision policy (DecP). In addition to this method, two other ad hoc methods based on track quality are described.

Modeling and synthesis of circular-sectoral arrays of log-periodic antennas using multilevel fast multipole algorithm and genetic algorithms Ergül, Özgür Salih (American Geophysical Union (AGU), 2007-06-19) Circular-sectoral arrays of log-periodic (LP) antennas are presented for frequency-independent operation and beam-steering capability. Specifically, nonplanar trapezoidal tooth LP antennas are considered in a circular array configuration, where closely spaced antennas occupy a sector of the circle. Electromagnetic interactions of the array elements, each of which is a complicated LP antenna structure, are rigorously computed with the multilevel fast multipole algorithm (MLFMA). Genetic algorithms (GAs) are ...
Development of an ultra wide band (UWB) array antenna Ceylan, Hasan Akın; Aydın Çivi, Hatice Özlem; Department of Electrical and Electronics Engineering (2022-4) Demand for ultrawideband antenna arrays in telecommunications, space and airborne platforms, RADAR applications and MIMO systems, etc. is rising consistantly. A modern approach to develop an ultrawideband array is to utilize the mutual coupling between array elements. Even though individual elements are of narrowband characteristic in isolated form, they gain ultrawideband performance in array configuration under strong mutual coupling. In this work, an ultrawideband tightly coupled dipole array antenna is ...
Amplitude Tapering Scheme for Through-Element Coupled Antenna Arrays Miran, Emre Alp; Koç, Seyit Sencer (2016-07-01) A new approach is proposed to achieve appropriate amplitude distribution for series-fed linear microstrip patch antenna arrays. Through element coupled patches are further investigated to attain more control on the level of the transmitted signal through the antenna elements. Power coupled to the next element is controlled by adjusting the size of the coupling region (CR) and the width of the gap to accomplish amplitude tapering. An empirical formulation is obtained through parametric analysis which can be ...
Study on Q-RAM and Feasible Directions Based Methods for Resource Management in Phased Array Radar Systems Irci, Ayhan; Saranlı, Afşar; Baykal, Buyurman (2010-10-01) Our recent progress and results on optimal real-time resource allocation in phased array radar systems are reported. A previously proposed discrete resource allocation approach, the Quality of Service based Resource Allocation Model (Q-RAM), is analyzed and is observed to generate nonoptimal results. We identify the shortcomings of this method and first extend it using the Karush-Kuhn-Tucker (KKT) optimality conditions for the single resource type case. We obtain an algorithm that delivers a globally optima...
Antenna Scan Period Estimation of Radars with Cepstrum and Scoring Kalfaoglu, M. Esat; Can, Ogul; Yildirim, Berkin; Alatan, Abdullah Aydın (2019-01-01) The performance of the cepstrum method on the radar antenna scan period estimation is evaluated. In addition, instead of relying on the cepstrum estimation directly, a two-block algorithm is proposed by adding a scoring block to make the estimation more reliable. Cepstrum is compared with zero-padded Fast Fourier Transform (FFT), zero-padded periodogram and Pulse Repetition Interval (PRI) transform. Cepstrum has been observed to be superior in six of the seven groups in the radar data set with respect to pe...
