In order to determine the time delay between the two periodic pulse signals (2, 5) in as accurate a fashion as possible, the invention proposes a device which is characterized by means for producing a periodic diagnostic signal (18), having half the frequency of the first pulse signal (2), whose sampling ratio is a measure for the time delay between the first pulse signal (2) and the second pulse signal (5) as well as means for determining the sampling ratio of the diagnostic signal (18) and means for determining the time delay between the first pulse signal (2) and the second pulse signal (5) from the sample ratio of the diagnostic signal (18).

摘要： A spread spectrum radar system, characterized in that the receive radar signal is mixed down to baseband and applied to leak cancellation means for subtracting therefrom an attenuated delayed version of the transmit radar signal to provide a reflected receive radar signal with improved signal-to-noise ratio for further processing and to prevent receiver saturation. The radar allows the capture of the range and speed of identified targets, and facilitates a determination of the target's direction. It exhibits an inherent immunity to electromagnetic interference, and is relatively undetectable by radar detectors. The system is easily reprogrammable for different range resolutions and permits Doppler processing to be independent of the angle between radar signal and the track of the target.

摘要： A radar device precisely detects a target in short time intervals by detecting a true peak frequency with high accuracy via a calculation which does not require a large amount of computation. A discrete frequency spectrum of a beat signal multiplied by a window function is determined, and values of signal strength at two discrete frequencies which are, respectively, higher and lower than a peak frequency of the discrete frequency spectrum of the beat signal and which are adjacent to the peak frequency. The frequency difference between the discrete peak frequency of the beat signal and the peak frequency of the window function is then determined from the ratio between the values of signal strength at those two discrete frequencies adjacent to the peak frequency. Thus, the true peak frequency of the beat signal is determined with a high frequency resolution.

摘要： A power regulator regulates the power provided to a transistor-based circuit, such as that which might be employed in a high stability MTI radar system. According to the invention, a variable reference voltage is controlled based on the frequency of operation. The output voltage of the power regulator is then modified accordingly. Preferably, the reference voltage is controlled based on the location of the target frequency in relation to the overall operational frequency band, which has been divided into a series of sub-bands.

摘要： A waveguide bi-directional amplifier module is illuminated by a downstream illumination source and an upstream illumination source. The illumination sources are coupled to an array having waveguide to microstrip converters that provide for upstream and downstream electrical signals. Switchable amplifiers provide for amplification in both directions for the electrical signals and the converters coherently combine the output of the amplifiers to provide increased power to the electromagnetic wave entering the waveguide.
