Synthetic range profile measurements with a pulse compression radar

Abstract

Abstmct -Monochromatic or pulse compression radars have a range resolution determined by the instantaneous bandwidth of the pulse. For surveillance radars, the range resolution must be set fairly coarse to reduce the output data rate. In order to obtain more specific information about a target, higher resolution would be more desirable. Synthetic range profiling (SRP) is a technique where successive radar pulses are radiated at different frequencies. This frequency domain information can be transformed to the time domain to obtain a high resolution range profile of a target over a small subdomain of the radar imaging area. This paper reports practical measurements made with a pulse compression radar. The measurements included static targets, simulated moving targets and a small aircraft.
