We present multifrequency radioheliograph observations of solar radio
noise storms. The data base consists of observations carried out over
7 different days in the spring months of 1992 and 1993. In all, we pre
sent about 82 hours of data with 1 s time resolution at 4 different fr
equencies between 164 and 410 MHz. The spatial resolutions in the EW a
nd NS directions vary with frequency from 1.2 to 0.8 and 3.7 to 1.5 ar
c min, respectively. In order to study the characteristics of bursts a
nd continuum, we have developed a method for separating them in the ti
me domain at each frequency. Our main results are: (i) there are no sy
stematic large-scale motions of the continuum, the position is usually
stable to within 2' of arc over durations of 3-4 hours and more; (ii)
the positions of the continuum at different frequencies are often clo
ser to each other than 1' of arc and have strongly correlated small-sc
ale motions; (iii) the bursts have their positions scattered over the
continuum extent and are slightly smaller in size than the underlying
continuum; and (iv) there is no evidence for bipolar structures. We di
scuss the implications of these results for the current models of nois
e storm emission and for the trapping of suprathermal electrons.
