DESCRIPTION:Radio and radar instrumentation plays a key role in the observ
 ation of the space environment.  Ground based radio instrumentation has pr
 ovided a sustained record of observation and scientific discovery for stud
 y of the Geospace environment.  On-going technological trends\, such as th
 e exponential improvement in computing technology\, have greatly changed h
 ow we operate existing instrumentation and the capabilities which are poss
 ible in future designs.  Recent efforts have led to the development of rad
 io arrays which have extraordinary capabilities.  To date the majority of 
 theses instruments have been developed and used for applications in Radio 
 Astronomy.  Radio arrays can be constructed in a wide variety of scale siz
 es and spatial distributions.  When combined with one or more transmitters
  it is possible to produce active radar systems or passive radars using tr
 ansmitters of opportunity.  Advanced radio arrays are digital instruments 
 with measurement techniques implemented as software running on high perfor
 mance computing systems.  This computing capacity is used to control\, fil
 ter\, and interpret the flow of information from the sensor elements.  In 
 many cases this information can be used to simultaneously address multiple
  applications and this ability can be enhanced with appropriate instrument
  design.  When applied to Geoscience\, advanced radio arrays can provide a
  wide range of scientific capability and enable measurements from the lowe
 r atmosphere\, into the ionosphere\, through the heliosphere\, and to the 
 surface of the Sun.  The principles by which we design such instruments ar
 e guided by the scientific scope we allow ourselves.  This scope determine
 s the potential for enabling future discoveries and is a key element in th
 e overall value of the instrumentation to society.  I will discuss future 
 technological trends which will shape the next generation of Geospace radi
 o arrays\, define the principals for guiding their development\, and highl
 ight examples from on-going work which inform us of their potential for me
 asurement of the space environment.\n
