A closely related technique useful for localized gas concentrations and leaks is photoacoustic detection and ranging (padar) (90). A laser pulse tuned to an absorption line generates an acoustic signal that is detected by a paraboHc microphone. A range resolution of 1 cm out to 100 m is feasible. [Pg.315]

In addition, critical performance parameters, such as range, resolution, and user requirements, can help identify the appropriate equipment to be used for specific measuremenfs. Calibration dates/schedules, and also tiie sfafus of fhe insfrumenf and componenfs (active, out of tolerance, retired, or awaiting service), can be tracked. [Pg.1040]

Spectral width, dynamic range, resolution and sensitivity are expected to be pushed toward further limits. An emerging advancement in NMR spectroscopy is the DOSY technique (Section 5.4.1.1) which offers a separation capability as a function of the rates of steady state diffusion of molecules in solution.

The choice of an analyzer depends on the kind of studies and applications that will be carried out m/z range, resolution, mass accuracy, scan speed, number of mass separations, are some of the parameters that have to be considered. [Pg.55]

Here we introduce the principles of bistatic and multistatic radar. Firstly, we examine what is meant by these terms and then go on to develop the fundamental relationships that govern performance in terms of sensitivity, coverage, range resolution, Doppler resolution and target location accuracy. This provides the essential information necessary to understand the advantages and disadvantages of bistatic and multistatic radar operation for candidate applications. More detail can be found in the excellent text of Willis [1]. [Pg.2]

Range resolution is the ability of a radar system to distinguish two closely spaced targets at differing ranges. In monostatic radar this is primarily a function of pulse length or modulation bandwidth. Azimuth... [Pg.10]

In the first instance cross-range resolution is determined by the product of the range and beamwidth 9 b- The beamwidth is determined by the size of the aperture d and thus cross-range resolution is given by... [Pg.172]

In an UNB radar the finite bandwidth of the radar signal limits the range resolution. However, this resolution can be recovered by multistatic measurements over a range of angles. Figure 6 shows four examples, and the Fourier space sampling corresponding to each. [Pg.177]

Range Resolution. Let r represent the output pulse length and Tr the pulse repetition interval. Pulses travel along the slant range and interact with the ground through the mainbeam as well as the sidelobes of the antenna array as shown in Fig. 13. [Pg.199]

Each pulse travels along the slant range and hence the slant range that can be recovered unambiguously is of size Thus, slant range resolution is given by... [Pg.200]

Translating to the ground plane, since the pulse wavefront is perpendicular to the slant range direction, we get the range resolution on the ground to be... [Pg.200]

For data acquisition a classical linear FMCW waveform is used which consists of four individual chirp signals (see Figure 7) and covers a bandwidth of 1GHz, which corresponds to a range resolution of 0.4m under realistic signal processing conditions. This waveform combines high ac-... [Pg.300]

Triple quadrupole mass spectrometers, QqQ, have almost become a standard analytical tool for LC-MS/MS applications, in particular when accurate quantitation is desired (Chap. 12). Ever since their introduction [124-126] they have continuously been improved in terms of mass range, resolution, and sensitivity (Fig. 4.38). [127-129]... [Pg.152]
