Radar Ranging

Radar range velocity measurement and range velocity resolution... 

The absorption of radiation (for NMR, in the radio wave range, 10-80 MHz, or in the radar range, up to 1 GHz for EPR, in the microwave range, 3-100 GHz) depends on the relative population of the ground, or lower (1) state and first excited, or upper (u) state, that is, it depends on a Boltzmann factor of the type Nu/N exp (—AE/kBT), where AE is the relevant energy difference. 

Radar is the acronym for radio detection and ranging1. This means that electromagnetic waves are used to measure the distance between a radar antenna and an obstacle. The simple form of the radar equation expresses the maximum radar range Rmax in terms of the key radar parameters and the radar cross section of the target. 

Part between the visible light and radar range of the electromagnetic spectrum, which corresponds to radiant heat.

Radar, conventional Electronic ranging device that transmits radio signals and then detects returned (scattered and reflected) signals the return signal strength (normalized for radar range) is proportional primarily to the size, type, and concentration of hydrometeors within the radar sampling volume. 

The state-of-the-art in component development for the major system components is discussed here, but first a few words concerning one of the more basic radar performance metrics, signal-to-noise ratio, and the performance of components as related to that metric. Since the radar range equation has a factor of in the denominator, the system SNR must improve by a factor of 16 relative to some baseline value, to... 

As defined here and used in the radar range equation, gain is strictly due to passive components and does not include active component (amplifier) gain associated with the transmitter subsystem. This distinction is important in estimating the performance of solid-state active arrays. 

The radar range equation was introduced in Sec. 17.1 In practice, estimation of the composite system loss factor and the system noise temperature can be very demanding. 

Infrared. Part of the electromagnetic spectrum between the visible light range and the radar range. Radiant heat is in this range, and infrared heaters are much used in GRTP processing.
