"An improved Correlation Height Analysis (CHA) algorithm is described and further supporting evidence for its effectiveness is provided. The underlying principles are the same as the original CHA algorithm, namely; (a) modelling the behavior of tracking radars in the low-angle region; (b) comparing results of the model with measured data in a correlation process, and (c) selecting the true track from the family of tracks provided by the correlator. The improvements to be discussed are concerned mainly with increasing the efficiency and robustness of the algorithm. The most significant is the procedure for effecting item (c). In addition, a description is given of the software implementation of the algorithm together with the sampled-aperture radar facility used to record data for testing the algorithm. CHA low-angle tracking is demonstrated using experimental data recorded with this facility (U)"--Abstract, page 1. Issued also in print format. Tracking radar. Algorithms. Radar de poursuite.
