And a method of controlling the short-pulse radar low power consumption and small size that can be varied arbitrarily high time resolution the time delay between transmission and reception

摘要

In the control method thereof and a short-pulse radar of the present invention, a variable cycle pulse output from the variable-period pulse generator including (DDS) direct digital synthesizer, a reference timing the timing of the level transition in the first after receiving the search instruction and outputs as the transmission trigger signal by generating a signal whose level transition delay fixed time period from the reference time or reference timing thereof, the level transition in the timing of the integer multiple or delayed a half period of the variable-period pulse from the output timing and output as a reception trigger signal by generating a signal. The advance, by based on the relationship between the delay time between transmission and reception and the frequency data stored in the memory, varying the frequency data of the DDS, the variable delay time between the reception trigger signal and transmitting the trigger signal can be. Thus, with a simple structure, and can be varied as desired with high time resolution delay time between transmission and reception and low power consumption.
