Abstract

Statistical models are employed to represent both clutter characteristics and reflecting signals in the radar and telecommunication receivers. Rayleigh distribution is the simplest fading model in NLOS channels whose accuracy is lower than required in high-resolution radars and distant telecommunication receivers. At present, high accuracy models such as the m-type Nakagami and hybrid K and GK distributions are utilized in order to model fading. Although in NLOS channels, Non-Rayleigh models have better precision than Rayleigh models, the accuracy of these models decreases when the radiation angle in the transmitter and the reflection angle in the receiver are different. Whilst the K model has previously been introduced to describe the clutter properties of the radar, in this paper both K and F distribution functions are analytically introduced and deployed to model the fading using practical data.
