Passive Radars:
Advantages and disadvantages[edit]
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[3]
- Rapid updates, typically once a second
- Difficulty of jamming
- Resilience to anti-radiation missiles.

Alim radar system - Wikipedia, the free encyclopedia
Alim is the first
Iranian passive radar. Passive radars do not transmit waves and instead, detect and track objects by processing reflections from non-cooperative sources of illumination in the environment, such as commercial broadcast and communications signals.
Alim is cheaper and has less maintenance cost than normal radars because it doesn't have transmitter and movable mechanical parts. Although it needs high processing power because it has to do six levels of processing to track a target. Other advantages include the ability to detect low
RCS stealth targets in low altitudes. Also as it doesn't transmit anything, it is not possible to destroy it using
anti radiation missiles such as American
AGM-88 HARM thus it can be deployed near the enemy lines.
There are many Iranian radars with stealth detection ability and very powerful ECCM capabilities:
For example: I can recall one Iranian Stealth detection radar:
Matla - ul-fajr 2 Radar:
State-owned
Mashregh News reported that Matla-ul-fajr 2 is a solid state
3D radar operating in VHF band. Due to the nature of its frequency, it can detect low-
Radar cross-section targets such as
stealth aircraft and
cruise missiles. The range of the radar is 480 kilometres (300 mi) and it uses two separate channels for detection and is installed on the back of heavy trucks to enhance mobility. This radar won the first place in Kwarazmi International Festival.

I don't claim Iran will be able to shoot down all B-2 and F-22s when attacking Iran but I,m sure that, first, Iran can detect them soon enough to prepare for it.. second, They can shoot significant numbers of them...
Btw, Block Buster bombs are too heavy to be able to be carried by planes other than B-2... which we have done a lot for this specific bird!!
