Types of Sensors Although there are a number of remote sensing systems capable of collecting information, there are two general categories: • Passive sensors collect natural radiant energy reflected or emitted from a targeted object. • Active sensors transmit . What is Remote Sensing? “Remote Sensing is defined as the science and technology by which characteristics of objects of interest can be identified without direct contact” Concept of Remote Sensing Earth observation from space and air Remote Sensing is a technology to observe objects' size, shape and character without direct contact with them. These are: 1) Multispectral imaging sensor systems, 2) Thermal remote sensing systems, and 3) Microwave radar sensing systems. The multispectral or multiband imaging systems may use conventional type camers or may use a combination of both cameras and scanners for various bands of electromagnetic energy.

30 Principles of Remote Sensing. Types of Remote Sensing Remote sensing can be either passive or active. ACTIVE systems have their own source of energy (such as RADAR) whereas the PASSIVE systems depend upon external source of illumination (such as SUN) or self-emission for remote sensing. What is Remote Sensing? “Remote Sensing is defined as the science and technology by which characteristics of objects of interest can be identified without direct contact” Concept of Remote Sensing Earth observation from space and air Remote Sensing is a technology to observe objects' size, shape and character without direct contact with them. Types of Sensors Although there are a number of remote sensing systems capable of collecting information, there are two general categories: • Passive sensors collect natural radiant energy reflected or emitted from a targeted object. • Active sensors transmit . Remote Sensing: Introduction and Basic Concepts Basic concepts of remote sensing D Nagesh Kumar, IISc, Bangalore 9 M1L1 Fig. 7 Components of an ideal remote sensing system 8. Characteristics of Real Remote Sensing Systems Real remote sensing systems employed in general operation and utility have many. These are: 1) Multispectral imaging sensor systems, 2) Thermal remote sensing systems, and 3) Microwave radar sensing systems. The multispectral or multiband imaging systems may use conventional type camers or may use a combination of both cameras and scanners for various bands of electromagnetic energy.2 Electromagnetic energy and remote sensing. 49 The electronic document ( PDF A number of new sensor systems is added to Chapter 5 on Multispectral. imaging systems where the following seven elements are involved. Note, however that remote sensing also involves the sensing of emitted energy and the .
