33rd European Microwave Conference, 2003, 2003
A stepped frequency continuous wave radar for detecting flush buried and surface laid anti personnel landmines was designed and built. The system covers a frequency band from 400 MHz up to 4845 MHz. The range resolution is 3.4 cm and the maximum unambiguous range is 4.3 m. The antenna set up is a bi-static one with two Archimedean spirals with opposite

2019 International Conference on Advances in Computing, Communication and Control (ICAC3), 2019
The flexibility in the selection of waveforms indicates the performance of Radio Detection and Ranging(RADAR) system. These waveforms help in separation and identification of two targets, which are closely spaced in range or traveling near to each other by the the same speed.

2004 International Waveform Diversity & Design Conference, 2004
The specification of the waveform employed by any radar system has always been a key factor in determining performance and application. In recent years there has been a trend towards ever greater degrees of digitization and more widespread use of solid state power amplification in radar systems.

2008 IEEE Radar Conference, 2008
A multi-input multi-output (MIMO) radar system, unlike a standard phased-array radar, can transmit multiple probing signals that are correlated or uncorrelated with each other. This waveform diversity offered by the MIMO radar is the main reason for its superiority over the standard phased-array radar.

Most modern radars use a phase-modulated carrier for range and range-rate measurements. High carrier frequencies are generally selected when the application requires narrow beamwidths with a constrained aperture area. However, for applications which require the unambiguous determination of both range and range-rate, the high carrier frequency seriously

Orthogonal waveforms for FMCW MIMO radar
2011 IEEE RadarCon (RADAR), 2011Multiple input/multiple output (MIMO) radar system performance benefits from the capability to simultaneously transmit and receive multiple orthogonal waveforms. For pulse radars fitting orthogonal waveforms have been developed. These waveforms are however not necessarily suitable for frequency-modulated continuous-wave (FMCW) radar.

Detection performance is optimized and range and doppler both improved by maximizing the SNR. Since this needs the pulse to have high energy, long pulses are required unless a very high power transmitter is available. Long pulses also permit good doppler accuracy, but, for simple pulses, give poor range accuracy.
