Abstract: There is insufficient understanding of backscattering and attenuation for the radiowave remote sensing of snow because ground measurements of snow in the Ka-band are limited. This study estimates the equivalent radar reflectivity factor (Z e) and specific attenuation (k) of snow using a dual Ka-band radar (KaR) system comprising two identical Ka-band instruments. Radar - Radar - Factors affecting radar performance: The performance of a radar system can be judged by the following: (1) the maximum range at which it can see a target of a specified size, (2) the accuracy of its measurement of target location in range and angle, (3) its ability to distinguish one target from another, (4) its ability to detect the desired target echo when masked by large. attenuation-correction algorithms that may be applied, though most of these concern monitoring over an ocean surface where the surface reference technique is avail-able. They comment that the use of their forward-correction algorithm requires a well-calibrated radar. In this paper we report an analysis of data .

Radar Functions • Normal radar functions: 1. range (from pulse delay) 2. velocity (from Doppler frequency shift) 3. angular direction (from antenna pointing) • Signature analysis and inverse scattering: 4. target size (from magnitude of return) 5. target shape and components (return as a function of direction) 6. moving parts (modulation of. ONE-WAY RADAR EQUATION / RF PROPAGATION The one-way (transmitter to receiver) radar equation is derived in this section. This equation is most commonly used in RWR or ESM type of applications. The following is a summary of the important equations explored in this section: ONE-WAY RADAR EQUATION Peak Power at Receiver Input. variables (radar reflectivity Z and specific attenuation k), and total path integrated attenuation (PIA) estimates at X-band. The analysis concerns single frequency, incoherent and non-polarimetric radar systems. Two attenuation correction algo-rithms, based on a forward and a backward implementation respectively, are studied.

SUMMARY This paper introduces to the lecture series dedicated to the knowledge-based radar signal and data processing. Knowledge-based expert system (KBS) is in the realm of artificial intelligence.
