Abstract:
A radar system for acquiring a target comprising:a waveform generator for generating a programmable pseudo-noise (PN) code of a variable code modulation frequency and a variable chip length, a transmitter for transmitting a continuous wave (CW) radar signal modulated in accordance with the programmable PN code, a receiver adapted to receive a radar return based on the transmitted radar signal, and a processor for processing the received radar return and acquiring the target, such processor including a first tuning control signal provided to the waveform generator for adjusting the code modulation frequency, and a second tuning control signal provided to the waveform generator for adjusting the chip length, wherein the waveform generator adjusts the code modulation frequency and the chip length, in response to the first and second tuning control signals, to optimize target acquisition.
