Method and device for determining target speed and distance with frequency modulated pulses

摘要: Frequency-modulated wave trains are used in target locating by means of transmitted pulses and evaluation portions reflected the relation to bearing, distance speed, wherein pulse length bandwidth pre-selected. The received signals evaluated Doppler channels calculation ambiguity function. To make possible an increase accuracy speed determination with same number channels, frequency train within is calculated accordance irrational function, exponent which has a value between 0 1. smaller value, while keeping length, greater sensitivity. This method for modulating can be advantageously employed identification sound waves electromagnetic waves.
