The removal of coexisting land and weather clutter signals is a common problem in many radar applications. Although the optimal method for land-weather clutter suppression is known, it is usually not amenable to implementation due to computation and storage limitations of the processor. We propose an alternative method that employs low rank approximations on weather clutter correlation matrix to obtain detectors which are feasible to implement. The performance of the proposed method is compared with the optimal detector and some other detectors used for this task to illustrate the trade-off between the improvement factor gain and the computational, storage requirements.

On the design of staggered moving target indicator filters ISPIR, Mehmet; Candan, Çağatay (Institution of Engineering and Technology (IET), 2016-01-01) The problem of moving target indicator (MTI) filter design for radar systems with non-uniform (staggered) pulse repetition intervals is examined. The goal is to realise and then utilise a trade-off in the design of MTI filter between the conflicting requirements of high suppression of undesired signal (clutter echo) and minimal suppression of desired signal (target echo). To that aim, three design methodologies, namely, least squares, convex optimisation and min-max error, are studied. The numerical results...
Efficient Methods of Doppler Processing for Coexisting Land and Weather Clutter Candan, Çağatay; Yılmaz, Ali Özgür (2008-05-30) The joint suppression of returns from land and weather clutter is required in many radar applications. Although the optimal method of land-weather clutter suppression is known, the solution is usually not practical to implement. In this paper, we propose a method that employs rank-1 and rank-2 approximations on the weather clutter correlation matrix to obtain suboptimal but simpler detectors which are easier to implement. The performance of the proposed detectors is compared with the optimal detector and so...
Milimeterwave FMCW radar design İçöz, Dilşad; Hızal, Altunkan; Department of Electrical and Electronics Engineering (2009) In traffic radar system, Frequency Modulated Continuous Wave (FMCW) will be used since these radars are preferred in short distance and high range resolution systems. The system to be constructed is not only a system operating with Doppler principle and detection of speed; on the contrary a functional radar is planned to be produced. In various traffic radars in use, Doppler shift constituted by the targets causing high reflection within detection field is measured and the measured speed corresponding to th...
Collaborative mobile target imaging in ultra-wideband wireless radar sensor networks Arık, Muharrem; Akan, Özgür Barış; Department of Electrical and Electronics Engineering (2008) Wireless sensor networks (WSN) have thus far been used for detection and tracking of static and mobile targets for surveillance and security applications. However, detection and tracking do not suffice for a complete satisfaction of these applications and an accurate target classification. To address this need, among various target classification methods, imaging of target yields the most valuable information. Nevertheless, imaging of mobile targets moving over an area requires networked and collaborative d...
Linear prediction for single snapshot multiple target doppler estimation under possibly moving radar clutter Öztan, Baha Baran; Tanık, Yalçın; Department of Electrical and Electronics Engineering (2008) We have devised a processor for pulsed Doppler radars for multi-target detection in same folded range under land and moving clutter. To this end, we have investigated the estimation of parameters, i.e., frequencies, amplitudes, and phases, of complex exponentials that model target echoes under radar clutter characterized by antenna scanning modulation with observation limited to single snapshot, i.e., one burst. The Maximum Likelihood method of estimation is presented together with the bounds on estimates, ...
