Ground penetrating radar (GPR) is a technology that uses pulses of electromagnetic energy sent into the ground to create reflections from the ground compositions and objects within the ground. These reflections can then be analyzed by software and turned into a plot or map projection so that objects within the ground can be identified or ..

Synthetic aperture radar (SAR) and inverse SAR (ISAR) are methods of using radar to map a stationary object, more usually terrain. SAR/ISAR systems are deployed on aircraft or satellites that move at high velocities in respect to the surface of the earth or potentially any stationary object or terrain. SAR/ISAR benefits from the phenomenon that ..

Chirp Radar is a type of radar that uses frequency modulation and pulse compression (which may confuse many as chirp has also been used as a synonym for “pulse compression”), which combines the capabilities of frequency modulation and pulse radar. Some of the benefits of a Chirp radar over a simple pulse radar are range ..

A continuous wave (CW) Doppler radar can be augmented via the use of frequency modulation. This type of radar is known as a frequency modulated continuous wave (FMCW) radar. The use of frequency modulation allows for the detection of both range and target velocity, as well as the ability to discriminate between multiple targets. A ..

A pulsed radar is a sensing system that uses a high power pulsed signal reflected off of objects to determine their distance from the radar antenna. The basic operation of a pulse radar is that a pulse modulator generates a short pulsed which is then amplified. The amplified pulse then passes through a duplexer or ..
