azimuth resolution

The ability of radar equipment to separate two reflectors at similar ranges but different bearings from a reference point. Normally the minimum separation distance between the reflectors is quoted and expressed as the angle subtended by the reflectors at the reference point.

In different working modes, the azimuth resolution ability is listed in the order TOPS < sliding spotlight < spotlight, whereas the surface coverage is listed in the reverse order.

A Bistatic Imaging Method for GEOSAR in the Strip Mode and UAVSAR in the Steering Beam Mode

Firstly, if we want high azimuth resolution, the azimuth synthetic aperture is also very long, which will cause huge sampling number.

Downward-Looking Linear Array 3D SAR Imaging Based on Multiple Measurement Vectors Model and Continuous Compressive Sensing

In principle, by combining with SAR techniques, current commercial short range radar products can achieve very high azimuth resolution, and therefore additional applications are expected.

Micro-Air-Vehicle-Borne Near-Range SAR with Motion Compensation

Here, as in single-look SARs, the high range resolution is commonly achieved by using a linear frequency modulation (LFM) of the transmitted radar pulses, whereas the high azimuth resolution is obtained by a coherent processing of the consequent backscattered radar pulses.

Effects of local phase errors in multi-look SAR images

The azimuth resolution [[rho].sub.a] can be expressed as Equation (3) [4].

Study of ionospheric effects on azimuth imaging for Medium-Earth-Orbit SAR

For these systems operating at low frequencies, e.g., the VHF/UHF band, or at higher frequencies (usually more than 1 GHz) with super high azimuth resolution (0.5m or higher), motion compensation (MoCo) is quite a challenge.

Improved motion compensation for wide-beam wide-swath airborne SAR

SAR measurements use relatively simple antennas with a small aperture length and, therefore, poor azimuth resolution. By translating the sensor as shown in Figure 5 appropriately and coherently combining received signals from the different azimuth positions, the equivalent physical length of the aperture can be increased.

Performance of 2D compressive sensing on wide-beam through-the-wall imaging

However, the image formed by conventional radar (so-called real aperture radar, RAR) was poor in azimuth resolution.

Design and development of a C-band RF transceiver for UAVSAR

Although True Flight isn't slicing the loaf that thin, its display, as shown here, will split the XRX's quadrants, dividing the azimuth resolution into eight segments.

Zaon XRX traffic: affordable azimuth: we were impressed with the XRX's range and azimuth capability. But we think it will need an external antenna to see traffic behind the airplane

The azimuth resolution available from such a beam is dependant on range, increasing with distance.

By the Doppler's sharp stare

Narrow beam widths are required for added azimuth resolution. But shorter pulses result in less average power and narrow beams demand higher frequencies or larger antennas.
