The problem of radar target detection in Weibull and range-heterogeneous clutter is considered. The clutter component in each range cell is modeled as an instance of a random variable belonging to one of several Weibull distributions. We use the expectation-maximization algorithm to estimate parameters of the distribution and set the threshold accordingly. The performance of the proposed receiver is investigated through computer simulations and observed to be superior compared with numerous well-known methods.
