Conventional Mills Cross architecture suffers from poor direction-of-arrival angle estimation accuracy in the dimension that the transmitter is aligned. To improve the estimation accuracy, a space-time coded, multiple-input multiple-output (MIMO) direction finding method, with complementary codes is presented. The performance of the suggested MIMO Mills Cross architecture has been evaluated by underwater field experiments. Field experiments confirm the feasibility of the proposed approach and illustrate the performance gains. Since the proposed approach does not require any changes in the conventional Mills Cross hardware, the performance improvement can also be realized by a software reconfiguration for existing legacy systems.

A Hybrid Antenna Element for Travelling Wave Dual-Plane Monopulse Slotted Waveguide Arrays Gültepe, Gökhan; Doğan, Doğanay; Aydın Çivi, Hatice Özlem (2018-12-10) A novel antenna element for low loss and low-profile dual-plane monopulse arrays is proposed. The travelling wave array has both sum and difference distributions in azimuth. The designed element is the unit cell of an interleaved slotted waveguide array feeding wideband printed antennas via probes inserted into waveguides from the slots. The use of printed antennas enhances the narrow sidelobe and efficiency bandwidth of the closely-spaced slotted waveguide arrays by up to 20%. The unit cells are modelled a...
Design and evaluation of V-shaped arrays for 2-D DOA estimation Filik, Tansu; Tuncer, Temel Engin (2008-04-04) A new method for optimum design of V-shaped arrays is presented for azimuth and elevation angle estimation simultaneously. The design criterion is based on the Cramer-Rao Bound (CRB) for joint estimation where the coupling effect between the azimuth and elevation direction of arrival (DOA) angles is taken into account. The design method finds an optimum angle between the linear sub-arrays of the V-array. The computation of the optimum angle is simple due to the monotonic characteristics of the best and wors...
A Study on the Performance of a Complementary Auxiliary Antenna Pattern for Maisel Sidelobe Blanker DINLER, Dogancan; Candan, Çağatay; KOC, Sencer (2018-04-27) The problem of coupling between probability of target blanking (P-TB) and probability of blanking (P-B) in Maisel sidelobe blanker (SLB) is addressed and a complementary auxiliary antenna pattern is proposed for phased array radar systems. The numerical results indicate that the complementary pattern provides an improvement on P-TB and P-B especially for the cases where antennas have poor mainlobe-to-sidelobe ratio.
An Adaptive fast time radar receiving filter for minimization of clutter and time side-lobes Özdemir, Seçil; Tanık, Yalçın; Department of Electrical and Electronics Engineering (2013) In this thesis, a maximum likelihood receiver to obtain the target range profile that uses the clutter prediction derived from the target-free previous observations is suggested as a fast time processor for pulse compression radar systems. The maximum likelihood receiver is proposed to overcome the range sidelobe problem, which is introduced by the pulse compression method. Conventional methods, such as the matched filter receiver, as fast time processor result in the targets with high radar cross sec- tion...
Phased array antenna calibration and experimental validation Yalım, Alper; Demir, Şimşek; Department of Electrical and Electronics Engineering (2013) In this thesis, nine different methods aiming calibration of Phased Array Antenna (PAA) and Multifunctional Radars which employ PAA are presented. Those calibration methods are described, procedures of the methods are explained in detail, and information about constraints and measurement restrictions of those methods is given. As one step further, comprehensive work is focused on Multi-Element Phase Toggling (MEP) method and Rotating Element Vector (REV) method. Results of simulations are shown, theoretical...
