A New Age of SAR: How Can Commercial Smallsat Constellations Contribute to NASA's Surface Deformation and Change Mission?

open access: yesEarth and Space Science, Volume 12, Issue 1, January 2025.
Abstract In response to the 2017 Decadal Survey, NASA conducted a five‐year study on the Surface Deformation and Change (SDC) designated observable to study potential mission concepts. As part of the SDC mission study, the Commercial Synthetic Aperture Radar (ComSAR) subgroup was tasked with evaluating the current landscape of the SAR and ...

Air target detection using airborne passive bistatic radar

open access: yesElectronics Letters, 2010
Passive bistatic radar (PBR) research has traditionally focused on using a static ground based receiver for air target detection. Reported are the initial findings from a novel airborne PBR experiment using commercial FM transmissions between 88 and 108 MHz, as illuminators of opportunity.

Adaptive Moving Target Detection for Forward Scatter Radar When the Noise Power Mismatch Occurs

open access: yesElectronics Letters, Volume 61, Issue 1, January/December 2025.
1. The problem of detecting moving targets with forward scatter radar is discussed. 2. The noise power mismatch, namely, the noise power in the secondary data and the noise power in the primary data differing by a noise‐scaling factor, is considered. 3.

RECOGNITION OF PROPELLER-DRIVEN AIRCRAFT IN A PASSIVE BISTATIC RADAR

open access: yesИзвестия высших учебных заведений России: Радиоэлектроника, 2018
Nowadays passive bistatic radars (PBR) allow for detection, determination of coordinates and tracking of moving objects. In order to enable PBR integration into air traffic control systems, it is necessary to solve the problem of recognizing airborne ...

Joint Ultra-wideband and Signal Strength-based Through-building Tracking for Tactical Operations

open access: yes, 2013
Accurate device free localization (DFL) based on received signal strength (RSS) measurements requires placement of radio transceivers on all sides of the target area. Accuracy degrades dramatically if sensors do not surround the area.
