Use of radio waves is a very common choice for proximity fuzes. The stand-off distance for fuzes varies between a lower and an upper limit depending on the electromagnetic reflectivity of terrain (target). If the reflectivity of the terrain is comparably higher, the return power at the receiver reaches to the threshold level more quickly and the stand-off distance increases. The work presented here introduces an approach to estimate the height of airborne ballistic platforms more precisely compared with the conventional fuzes regardless of the reflection properties of the terrain. Independent measurements of the rate of change of voltage from the receiver and the rate of change of height (from Doppler shift) allow the height to be estimated when the terrain reflectivity is unknown.

Algebraic spectral moments based moving clutter parameter estimation and clutter suppression Oktar, Onur; Tanık, Yalçın; Department of Electrical and Electronics Engineering (2014) In many modern radar systems, it is desired to detect the presence of targets in the interference which includes clutter and noise. Various signal processing techniques are proposed to effectively suppress the clutter and increase the signal to interference ratio. To achieve optimum suppression, radar system must know clutter characteristics and process the radar echoes based on these characteristics. For ground radars, the clutter environment characteristics are relatively stable and predictable. These cha...
True-time delay structures for microwave beamforming networks in S-band phased arrays Temir, Kaan; Demir, Şimşek; Department of Electrical and Electronics Engineering (2013) True time delay networks are one of the most critical structures of wideband phased-array antenna systems which are frequently used in self-protection and electronic warfare applications. In order to direct the main beam of a wideband phased-array antenna to the desired direction; phase values, which are linearly dependent to frequency, are essential. Due to the phase characteristics of the true-time delay networks, beam squint problems for broadband phased array systems are minimized. In this thesis, diffe...
Optimization of vibration characteristics of a radar antenna structure Baran, İsmet; Özgen, Gökhan Osman; Ciğeroğlu, Ender; Department of Mechanical Engineering (2011) Radar antenna structures especially array antennas which are integrated onto structures of aerial vehicles are subject to dynamic structural and aerodynamic loads. Due to occurrences of these dynamic loads there will be certain dynamic deformations which affect the antenna’s performance in an adverse manner. The influence of deformations and vibrations are important on array antenna structures, since they cause a change in orientation of elements of the phased array antenna which affects the gain of the ant...
Frequency Modulated Continuous Wave Radar for Range Detection Kaya, Tevfik; Sahin, Enes Burak; Nesimoglu, Tayfun (2018-11-02) In this paper, a Frequency Modulated Continuous Wave Radar is built using radio frequency techniques. Radar can measure the nearest object's range from 2 to 30 meters with 1-meter range resolution. The design process was carried out by using computer-aided design techniques, and mathematical tools. The hardware prototype was built and measurements were carried out confirming successful operation of the range detection radar.
Parameter estimation of multicomponent micro-doppler signals / Yıldız, Hüseyin; Severcan, Mete; Department of Electrical and Electronics Engineering (2014) Vibrating and rotating parts on a radar target is known to generate frequency modulated echo signal which is called micro-Doppler signal. Micro-Doppler signals are commonly modeled as the sum of sinusoidally modulated signals and the parameters, such as amplitude, frequency, phase, of these modulations are useful in the identification of these targets. In this thesis, the parameters of micro-Doppler signals from helicopter targets are estimated for the classification of the helicopters. Time-frequency analy...
