range resolution

The ability of radar to distinguish between targets along the same azimuth but at different ranges. Two targets at close range appear as one blip. The range resolution is a function of the pulse width. See radar resolution.

Based on the simulated parameters listed in Table 2, we obtain the ideal range resolution to 1.87 m.
MUSIC, as determined through the Monte-Carlo simulation results and experimental results, the range resolution of the proposed method is similar to that of SP-MUSIC for various parameters.
The developed platform is a prototype and has to be considered as a feasibility study; in its current version the radar system allows a maximum range of four kilometers, with a resulting range resolution of about 1.5 meters.
OFDM-PCSF signals can essentially synthesize the instant narrow bandwidth into effective large bandwidth, which provides improved data rate and range resolution, with low Doppler sensitivity and computational complexity.
It is clear that the range resolution depends primarily on the frequency bandwidth.
Both OFDM-PM and OFDM-FM signals are created by phasemodulationorfrequencymodulationwhich maximizes power efficiency when permits high power amplifier (HPA) to function near saturation point and the robustness of multipath fading increases by OFDM and also the competency for range resolution. The HPA creates distortions which are non-linear in nature in transmitter part therefore the PAPR or amplitude fluctuations create OFDM structure very sensitive.
Range Resolution. When the range resolution is considered, the velocity components of the two targets along the direction of the bistatic bisector are the same, which means [zeta] = 0.
(b) For a given RF carrier of [f.sub.1], the shorter the interval K is, the higher the range resolution is.
A true USRP-based testbed is discussed in [11], but a low range resolution is achieved, and a high direct coupling is produced, thus limiting the available dynamic range.
The slant range resolution of SAR sensor, expressed as Equation (1), depends on the signal bandwidth.
Applications such as non destructive testing and concealed weapons detection require excellent range resolution in order to give capability to discern objects that are in close proximity [4, 5].
Again, a copper sheet is assumed as reference target and positioned at various distances, multiple of the theoretical range resolution, equal to 6 m.
