Basics of the active and passive types of remote sensing technology and examples of their practical implementations in various fields.
It may be split into active remote sensing (when a signal is first emitted from aircraft or satellites) or passive (e.g. sunlight) when information is merely recorded. In this paper we study about Remote Sensing ,its process , various types ,...

A transducer that works on the principle similar to the sonar or radar and estimate attributes of the target by interpreting is called an ultrasonic sensors or transceivers. There are different types of sensors that are classified as active and passive ultrasonic sensors that can be differentiated b...
Some examples of technologies that use passive sensors are: Photographic Thermal Electric field sensing Chemical Infrared Seismic Analog Sensors Analog sensors produce a continuous output signal or measurement. The classification of analog sensors is the same as active sensors. The analog signals are di...
They know that their opinion might not get along with the global majority of the workplace, so they avoid speaking their mind freely, which results in mixed signals that are often very obvious. Often,it’s probablybothif you can’t understand whether someone is using passive or aggressive com...
Radar has a number of advantages over passive remote sensing in the accurate measurement of the physical properties of clouds, such as the determination of cloud height, depth and particle size. Radar therefore provides a potentially improved method for cloud classification, especially for clouds with...

There are different types of attacks against wireless sensor networks. These attacks can be faced by a variety of measurements. Attacks are classified into two types the active attacks and passive attacks. In the active type attack, an attacker attempts to modify or detach the transmitted messages...
