ABSTRACT:
A short range, high resolution, radar system of particular use in training radar operators. The system transmits very short pulses of a radio-frequency (RF) signal at a very high pulse repetition frequency, PRF.sub.o. A signal pre-processor samples a received baseband radar signal and generates a time-expanded signal which is a replica of the real received radar signal, but with a much lower nominal pulse repetition frequency, PRF.sub.n. The signal pre-processor includes a sampling circuit which receives the baseband signal, and a timing circuit which controls the sampling circuit. The timing circuit operates by causing samples of the baseband signal to be taken at progressively later portions of subsequent pulses. While the radar system is particularly useful in demonstrating radar principles in a classroom setting, it has other applications.
