The Korean Solar Radio Burst Locator (KSRBL; Dou et al. 2009,<br />
PASP 121, ) is a state-of-the-art research instrument capable of<br />
addressing several basic and applied research goals. These include the<br />
study of solar activity, the ability to locate bursts on the solar disk,<br />
the study of radio frequency interference (RFI) mitigation, and the<br />
study of space weather effects of solar bursts on wireless<br />
communications and navigation systems. KSRBL takes its name from the<br />
operational goal of locating bursts within 2 arcmin on the solar disk, a<br />
region small enough to identify the active region within which the burst<br />
occurs. This is useful because solar flares that occur to the east of<br />
the central meridian on the Sun are less likely to cause severe<br />
geo-effects than are flares that occur to the west. Thus, KSRBL provides<br />
an all-weather monitoring of burst locations as a backup to satellite<br />
systems. The talk will discuss the technique KSRBL uses to locate bursts<br />
despite its small dish size (2.1 m). In addition to locating bursts,<br />
KSRBL\/s high frequency and time resolution allows the spectral<br />
characteristics of the burst to be studied in unprecedented detail.<br />
KSRBL is frequency-agile (frequencies can be measured in any order), and<br />
measures a 2 GHz bandwidth with a time resolution of 25 ms. By tuning<br />
every 100 ms, it can cover the entire 0.245-18 GHz range of the<br />
instrument in 1 s. The talk will include a discussion of some of the<br />
spectral features KSRBL will be able to resolve and study. <br />
<br />
Because KSRBL covers such a wide frequency range, it sees a lot of RFI,<br />
both continuous and intermittent. The continuous RFI is relatively easy<br />
to remove. Highly intermittent RFI, which may appear and disappear on<br />
millisecond timescales and skip around in frequency, is far more<br />
difficult to detect and remove. KSRBL uses an innovative technique<br />
called Spectral Kurtosis (or SK; Nita et al. 2007, PASP 119, ) to detect<br />
and remove this more difficult RFI, resulting in a clean spectrum<br />
largely free of contaminating noise. The talk will demonstrate KSRBL\/s<br />
RFI mitigation capability and briefly describe how the SK algorithm<br />
works. Lastly, the talk will discuss KSRBL\/s usefulness for<br />
investigating effects of solar bursts on GPS, cell-phone, and other<br />
wireless technologies.
