Masking Effect Mitigation for FM-Based Passive Radar via Nonlinear Sparse Recovery
IEEE Transactions on Aerospace and Electronic Systems, 2023Nowadays, most passive radars use cross-ambiguity function (CAF) computation for signal processing. Although it is easy to implement, the performance may degrade significantly due to the masking effect among multiple echoes when the waveform's ambiguity ...

Experimental Analysis of the Environmental Noise in Passive Radar Based on FM Radio
International Radar Symposium, 2022Passive radar does not have its own signal source. Consequently, it is fully dependent on the presence of other signals that it can use for its operation. These signals are not optimal from the radar point of view.

UWB Wire-Bowtie Array for FM-PCL Passive Radar
IEEE Transactions on Antennas and Propagation, 2022Passive coherent location (PCL) systems using commercial FM radio broadcast stations as illuminators of opportunity (FM-PCL) require an antenna system with a null in its radiation pattern for suppressing the direct path interference (DPI) from the ...

Potential of Reducing FMCW Radar Mutual-interference Using Nonlinear FM Signals
Radar, 2021The state-of-the-art automotive radars are mainly implemented by using linear frequency modulated continuous wave (LFMCW). Unfortunately, the widespread use of LFCMW increases mutual interference between automotive radars.

International Radar Symposium, 2021
Passive radar is still a dynamically developing field of technology. This is due to a number of advantages over the active radar. However, like any technique, it is not free from problems.

1972 Antennas and Propagation Society International Symposium, 1972
A second generation FM-CW radar sounder is described which has scanning capability and is fully mobile. The sounder is used as a remote sensor with unprecedented range resolution for fine scale structural details in the lower troposphere. Design considerations and performance characteristics of this new sounder are presented and examples of ...

On radar polarimetry in FM-CW radar
Proceedings of IGARSS '93 - IEEE International Geoscience and Remote Sensing Symposium, 2002This paper attempts to apply the principle of radar polarimetry to wideband synthetic aperture FM-CW radar and presents a basic polarimetric detection result of a linear target in a laboratory measurement. Although the principle of radar polarimetry has well been established for the completely polarized wave and for the monostatic case, it still needs ...

Optimized FM PCL Radar Waveform
2006 International Radar Symposium, 2006To make a balance between time of detection and resolution of detection in radar, it must select an optimized time interval for integrations and signal bandwidth. In this paper, a new algorithm for finding best width of window and bandwidth of the FM signals for FM PCL radar is designed.
