Abstract : The performance of the average likelihood and the maximum likelihood ratio tests is compared in detecting a slowly fluctuating target with a Rayleigh amplitude distribution and unknown doppler frequency. The study concludes that since the performance of the two tests does not differ significantly, implemention of the more complex average likelihood ratio detector is not warranted in search radars for the assumed target model.
