Upgrading two dimensional search radar to three dimensional search radar based on SDR

Abstract EN

This paper presents an exploitation of the existing two dimensional radars (2D) which have two identical antennas for reception to be upgraded to a three dimensional radar (3D) in order to measure the height as well as the slant range and azimuth direction.

The height measurement is important for preliminary information for reducing the time required for acquisition.

Software Defined Radio (SDR) is chosen for the implementation of height finder processor is given in this paper.

Design parameters are selected for the proposed height finder processor in order to accommodate SDR requirement.

This work is also concerned with the analysis of the parameters which affect the accuracy of height finding.

These parameters include the refraction index, smooth surface reflection, divergence and rough surface reflection.

The results of the analysis show the feasibility of this proposal to upgrade the 2D to 3D radars.
