The IADS should be able to detect TALDS. Implementation approach could be similar to HARM detection.
Once detected TALDs could be set to invisible, so SAM sites don't go live to fire on them

This video has some info on the flight profile of a TALD:

Think of adding logic so that talds flying close to each other would all be discovered if one TALD triggers TALD detection
