.... can also be used in automatic surveillance of large areas and they are robust to visibility conditions, which explains their use in various military applications, as in [2] There exist several sophisticated methods for estimating the DOA of propagating planar wavefronts efficiently and precisely [3, 4]. However, many of these methods become unusable in low SNR conditions, as noise corrupts the estimation results and observation reliability is compromised. Traditionally, methods have been divided into two main categories: conventional and parametric. Conventional methods (e.g. beamforming and ....

....the centre pixel are not given any higher weighting than those outside, so this is an ineffective way of preserving the corner structure. Other methods include the contrast dependent thresholded median (see [55] adaptive decimated median filtering (see [1] and the midrange estimator (see [2]) which places the brightness estimate halfway between the maximum and minimum local brightness values. Three similar filters, the first two of which are typical of more complicated order statistic operators, are the K nearest neighbour operator (see [13] the ff trimmed mean (see [5] and the ....
