The equivalent isotropically radiated power (EIRP) degradation due to random position errors in the location of the antenna elements in an array is derived through the expected value and standard deviation of the EIRP. The expressions are derived for a linear and a semicircular array (SCA). The minimum tolerance of the array elements is presented by means of the relationship between the EIRP degradation and a standard deviation or the uniform bound of the probability distribution. Using this tolerance, the output signal to interference and noise ratio (OSINR) is examined in the framework of adaptive processing using the direct data-domain least-squares (D3LS) approach.
