Advantages and Disadvantages
Advocates of the technology cite the following advantages:
- Lower procurement cost
- Lower costs of operation and maintenance, due to the lack of transmitter and moving parts
- Covert operation, including no need for frequency allocations
- Physically small and hence easily deployed in places where conventional radars cannot be
- Capabilities against stealth aircraft due to the frequency bands and multistatic geometries employed
- Rapid updates, typically once a second
- Difficulty of jamming
- Resilience to anti-radiation missiles
Opponents of the technology cite the following disadvantages:
- Immaturity
- Reliance on third-party illuminators
- Complexity of deployment
- 2D operation

Famous quotes containing the word advantages:
“... there are no chains so galling as the chains of ignorance—no fetters so binding as those that bind the soul, and exclude it from the vast field of useful and scientific knowledge. O, had I received the advantages of early education, my ideas would, ere now, have expanded far and wide; but, alas! I possess nothing but moral capability—no teachings but the teachings of the Holy Spirit.”
—Maria Stewart (1803–1879)
