I am trying to test and locate an active Wi-Fi transmitter by sniffing it. What are some of the ways I can do it? And after I locate the Wi-Fi, how do I predict its signal strength? I need some ideas.

For location you can use software like Xirrius wifi locator. For an estimation of signal strength you need to use RSSI

You can use

iw dev <ifname> scan

to find out the signal strength of the SSID in question as well as its frequency. To locate the transmitter you could calculate the distance to it using the information collected with the former command. If you scan in several locations you can increase your accuracy.
