As you’re about to find out, there arehundreds of remote sensing applicationsthat use passive and active sensors. But first, let’s dig a bit deeper into both types of remote sensing. Examples of remote sensing Now that we have a clear understanding of passive and active remote sensing, l...
Lower data requirements and usage.The data used in active monitoring is comparably lower than passive monitoring, as it involves specific and targeted tests during a specific period. Hence, data is more focused and related to specific performance metrics being tested, such as: Bandwidth Latency Thro...
Active wheel-speed sensors require power to operate, whereas passive units do not. There are two types of active wheel-speed sensors: a Hall-effect sensor and a magneto-resistive sensor. A Hall-effect sensor requires either a toothed or magnetic ring to generate a voltage signal, whereas a ...
active, the latter as passive microwave sensors. Active sensors are based on radio detection and ranging (Radar) technology and can be distinguished into imaging radars, altimeters, and scatterometers (Elachi 1988). Passive sensors work conceptually similarly to optical thermal sensors and are ...
If passive control systems are used enhancing structural damping, stiffness or strength, the other control techniques employ controllable forces to add or dissipate, or both, energy in a structure due to the specific devices integrated with sensors, controllers and real-time processes to operating. ...
Indeed, we show—through an accurate link budget based on ITU channel models—that active transmitters may actually generate harmful interference to highly sensitive sensors on satellites orbiting over communication systems. Shared access between sensing and communications has never been demonstrated ...

Active regeneration is a more controlled process that is started by the engine control unit (ECU). The ECU uses sensors to monitor the exhaust gas temperature, pressure and flow rate to determine when active regeneration is required. Extra fuel is sent to the exhaust, so that its temperatur...
