摘要: The invention relates to a radioaltimeter type detector comprising an oscillator-transmitter (10), modulator (20) suitable for frequency modulating the according given characteristic, mixer receiving signal from and corresponding echo reflected by target, discriminator circuit (50, 60) connected output mixer. According invention, includes digital memory (21) containing series of values defining modulation characteristic (10).
