The RADARs use complex techniques such as stagger PRI, jitter PRI with frequency agile characteristics. The frequency agile RADARs switch frequencies with in a pulse to get different types of advantages. Today lot of RADAR signal processing takes place on FPGA platform. These signal processing algorithms include pulse parameters estimation, deinterleaving of mixed pulse patterns, processing com...

Multiple input multiple output radars transmit partially coherent or noncoherent waveforms for improving spatial resolution or spatial diversity. While waveform design for SIMO radars concentrate on improving the delay and Doppler resolution characteristics, waveform design for MIMO radars involve optimization of delay, Doppler and spatial resolution characteristics. The resolution properties o...

In this paper, through wall moving target tracking by M-sequence UWB radar is described. For that purpose, the imaging method consists of radar signal processing phases such as raw radar data preprocessing, background subtraction, data fusion obtained by receiving antennas of radar, detection, localization and tracking itself, is used. Our paper is focused on last phase tracking. Here, new nonl...

The existence of non-radar radio frequency (RF) signals in the environment possessing radar-like characteristics make them ideal candidates for use in radar applications such as synthetic aperture radar (SAR). The orthogonal frequency division multiplexing (OFDM) specific Worldwide Interoperability for Microwave Access (WiMAX) waveform is one such example. Research at the Air Force Institute of...

Target reader group are engineering students who want to perform tests using pulsed or chirped signals. Current Radar development is focusing the area of signal processing. This is taken into account by this educational note, where the R&S® SMW / SMBV instruments on the transmitter side and R&S®FSW / FSV instruments on the receiver side are combined to a closed loop Radar system, performing rad...

The applicability of the mono-static radar cross section (RCS) for the weather radar (WR) and the wind turbines (WT) is evaluated by theoretical and numerical results. It is concluded that the RCS scheme is not applicable for objects on the ground and is not a useful parameter for the definition of safeguarding distances of WT to the WR. Proposals for a deterministic case by case numerical trea...

In a multi-static radar (MSR) the transmit/receive aperture is divided into a number of sub-apertures that can be placed in various locations relative to each other. These locations can be chosen to optimize the performance of the radar in terms of some specific task. Two multi-static approaches have been investigated: • Closely spaced apertures – distributed aperture radar (DAR) • Widely space...

For a typical FMCW automotive radar system, a new design of baseband signal processing architecture and algorithms is proposed to overcome the ghost targets and overlapping problems in the multi-target detection scenario. To satisfy the short measurement time constraint without increasing the RF front-end loading, a three-segment waveform with different slopes is utilized. By introducing a new ...

In many applications of ultra-wideband (UWB) radar a character of target motion is a priori not known and naturally can differ within a group of multiple targets. Usually a signal processing aimed at the positioning of only moving persons or only static persons leads to a loss of information. To solve this task, the utilization of combined processing based on detection of non-stationary signal ...

GB-SAR (Ground Based Synthetic Aperture Radar) for inspection of wooden and concrete walls and structures has been developed and the system was evaluated by test measurements. The GB-SAR system uses frequency bandwidth 1-10GHz, and it can acquire full polarimetric radar signal. Then Synthetic Aperture (SAR) Radar signal processing is used to reconstruct 3-dimenatioal images of inner structure o...
