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 ...

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.
