Frequency-agile fire control radar system |
摘要 |
A signal processing system for simultaneously transmitting a plurality of carrier frequencies and receiving certain of said frequencies to the exclusion of others. In a radar system employing the disclosed technique, a CW carrier and pulsed modulated carrier are transmitted simultaneously from a single antenna. The CW carrier and the echo frequency from the modulated carrier are received by a receiver protector circuit which passes the low power echo of the pulse modulated carrier to receiver processing circuitry while suppressing the CW carrier having a power level above a predetermined threshold. The receiver protector enables the use of plural carrier frequencies in a frequency agile system with decreased frequency separation.
