Passive warning radar had no real use on an agile ww2 fighter, even not on an agile ww2 day fighter. Enemy aircrafts - Bf-109s, Fw-190, Zeros, Franks, Tonys, etc. didn't have any search radar, what this tail warning radar could detect.

As I said "I believe it works just like a bat : transmits sond waves-----> Meets the barrier----->recieves sond waves."

the radar which fix on P-38/51 isn't the "radar" U mentioned.
It works without receive enenmy radar wave but the reflection wave
As U can see the picture above.-------sorry for my English ,hope U can Ignore my syntax mistakes
