Define Jammer-to-Signal Ratio (JSR) and its significance.

• A. JSR is the ratio of the target signal power to jammer power at the receiver; higher JSR indicates improved reception.
• B. JSR is the ratio of jammer power to the target signal power at the receiver; higher JSR indicates greater potential degradation of reception.
• C. JSR measures the time delay between jammer and target signals.
• D. JSR is a measure of how many jammers are present.

Answer: (B)
