A Low-Cost Microwave Radiometer for the Detection of Fire in Forest Environments

Microwave Radiometry Imaging for Forest Fire Detection: A Simulation Study

“…Also, taking advantage of the low-cost radiometer considered in the framework of this work [5,6], a network of radiometers can be considered to increase the monitored area [16]. Otherwise, it can be mounted aboard an unmanned aircraft vehicle (UAV) [17,18], although a permanent scan is not possible due to the maximum duration of each mission.…”

“…Since the radiometer is placed at an height of few meters, the upward atmospheric emission and the related optical depth have been neglected in (2). The computations of the radiometric temperatures were performed at 12.65 GHz, the operative frequency of the radiometer prototype developed in [5,6].…”

“…While actual single-spot fire measurements by a microwave radiometer are promising under different conditions and in particular in presence of obstacles [5,6], in order to make the radiometric system useful in practical situations a microwave image of the observed scene has to be constructed [7].…”

“…We will refer to the low-cost microwave radiometer operating at 12.65 GHz and developed for this purposes in [5,6]. Therefore, these simulations will assess the identification capability of little fires by means of microwave radiometry, exploring different environmental and operative conditions.…”

Experimental Implementation of a Passive Millimeter-Wave Fast Sequential Lobing Radiometric Seeker Sensor

“…Principal civil applications of such sensors concern surveillance [1,2] and navigation aid in adverse weather conditions [3], as well as concealed weapon and explosive detection in airports [4,5]. Military applications span from surveillance through radiometric imaging to precision targeting [6].…”
