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.

Prospects of FMCW-based frequency diverse array radar Cetiner, Ramazan; Cetintepe, Cagri; Demir, Şimşek; Hizal, Altunkan (2019-11-01) The linear frequency modulated (LFM) frequency modulated continuous wave (FMCW)-based frequency diverse array (FDA) radar concept is investigated in detail. The radar operates as a linear pulsed FMCW/FDA in the transmission (TX) mode while it operates as a pulsed FMCW/phased array (PA) in the receiving mode. The issues such as low signal-to-noise ratio (SNR) of FDA, the time-angle scanning and time-range ambiguities are studied. It is shown that the local instantaneous frequency bandwidth is much smaller th...
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...
Height Estimation for Ballistic Platforms using Differential Measurements Vural, Aydin; Sengul, Orhan; Demir, Şimşek; Hizal, Altunkan (2013-10-01) 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...
Distance Measurement by Phase Tracking Dogan, Ozan; Demir, Ibrahim; Aydin, Umut (2017-05-18) In this work, multi frequency continuous wave radar phase unwrapping and the target tracking algorithm are combined. In order to unwrap the wrapped measurement, the unwrapped range measurement or the predicted range is utilized. Methods are assessed with the simulations and field tests. Final tracked range accuracy is shown to be increased without an additional phase unwrapping procedure.
Frequency diverse array antenna with periodic time modulated pattern in range and angle Secmen, Mustafa; Demir, Şimşek; Hizal, Altunkan; Eker, Taylan (2007-09-27) A general analysis of a frequency diverse transmit array antenna with a periodic modulated pattern in range, angle and time is presented. This antenna array system makes a continuous scanning in range and angle without using any phase shifters. The scanning is achieved using the frequency diversity by inserting a small amount of progressive frequency shift to each antenna element. The theory shows that there is the same modulation pattern in time, range and angle by taking the remaining two parameters fixed...
