Clutter Rejection for FM Ranging Airborne Radar [PDF]
Journal of Electromagnetic Engineering and Science, 2023 In airborne radar, it is important to reject clutter signals to detect targets of interest. High pulse repetition frequency (HPRF) waveform provides robust detection performance in a clutter environment by separating clutter signals from the target echo ...

Synchronization of Monostatic Radar Using a Time-Delayed Chaos-Based FM Waveform
Remote Sensing, 2022 There is no doubt that chaotic systems are still attractive issues in various radar applications and communication systems. In this paper, we present a new 0.3 GHz mono-static microwave chaotic radar. It includes a chaotic system based on a time-delay to

Improving FM Radar Dynamic Range Using Target Phase Noise Cancellation
IEEE Journal of Microwaves, 2021 A method for improving the dynamic range of frequency-modulated continuous-wave (FMCW) radar systems is presented. Bright echo signals detected with FMCW radars can carry strong phase noise sidelobes, especially for radars at W-band and higher ...

Journal of Advances in Science and Engineering, 2020 A common technique used by military to realize low probability of intercept (LPI) is linear frequency modulation (LFM) in the field of electronic intelligence (ELINT). This paper estimates the pulse width (PW) and the pulse repetition period (PRP) of LFM

SAR: A Novel Application for FM-CW Radars [PDF]
31st European Microwave Conference, 2001, 2001 For small-scale earth observation applications, there is a special interest in low-cost, high-resolution imaging radars small enough to be operated from small, possibly unmanned, aircraft. The combination of the compactness of FM-CW technology and the high resolution of SAR systems should result in such a small, cost-effective imaging radar.

IJIREEICE, 2015 Global warming is one of the most important issues facing humanity. The depth and extent of sea-ice are clear indicators of global warming. Snow cover on sea-ice is an important variable that affects the volume of sea-ice and indirectly global warming as a whole. This paper discusses the design of snow radar.

On the Analysis of PM/FM Noise Radar Waveforms Considering Modulating Signals with Varied Stochastic Properties [PDF]
Italian National Conference on Sensors, 2021 Noise Radar technology is the general term used to describe radar systems that employ realizations of a given stochastic process as transmit waveforms. Originally, carriers modulated in amplitude by a Gaussian random signal, derived from a hardware noise

Generating nonlinear FM chirp waveforms for radar. [PDF]
, 2006 Nonlinear FM waveforms offer a radar matched filter output with inherently low range sidelobes. This yields a 1-2 dB advantage in Signal-to-Noise Ratio over the output of a Linear FM waveform with equivalent sidelobe filtering. This report presents design and implementation techniques for Nonlinear FM waveforms.
