Analysis of Efficiency of Long-Term Multi-Scanning Radar Observation Methods

In this paper we consider a surveillance radar using a multi-scanning observation method based on the well-known “track-before-detect” procedure. We analyse different approaches to estimating efficiency of long-term multi-scanning observation methods. The expected benefit of the methods is usually associated with detection range of radar. Detection range is increased due to long-term accumulation of signal energy. But it is necessary to consider not only detection range gain, but also the benefit related to obtaining of track data. We analyse the accuracy of trajectory parameters estimation and increase in tracks initiation range.
