Frequency-stepping system

An experimental system for obtaining frequency-averaged radar cross-section data and high range resolution data has been implemented in X band [1]. This has been incorporated into a pulsed radar, ground plane cross-section facility [2]. The transmitter and local oscillator frequencies are increased stepwise from pulse to pulse over a bandwidth of IGHz. Two useful techniques can be based on this: An averaging technique that reduces the violent oscillations commonly appearing on scattering patterns as a result of interaction between scattering centers on a target; a range resolution technique.
