Ranging success probability of PPP distributed automotive radar in presence of generalized fading
share
In automotive radar applications, multiple radars are used in all vehicles for improving the imaging quality. However this causes radar-to-radar interference from neighbouring vehicles, thus reducing the imaging quality. One metric to measure the imaging quality is ranging success probability. The ranging success probability is the probability that a multiple radar system successfully detects an object at a given range, under certain operating conditions. In state-of-the-art literature, closed form expressions for ranging success probability have been derived assuming no fading in desired signal component. Similarly in literature, though distribution of fading in interferers is assumed to be arbitrary, closed form expression is derived only for no-fading assumption in interferers. As fading is always present in a wireless channel, we have derived ranging success probability assuming desired channel experiences the popular Rayleigh fading. And we have assumed generalized κ-μ shadowed fading for interfering channels that generalizes many popular fading models such as Rayleigh, Rician, Nakagami-m, κ-μ etc. The interferers are assumed to be located on points drawn from a Poisson point process distribution. We have also studied how the relationship between shadowing component and number of clusters can affect the impact of LOS component on ranging success probability.
