rad-lab

A Python radar module for simulating pulse-Doppler returns and generating range-Doppler maps (RDMs). Designed for radar engineers and students who want to build intuition for how RDMs are formed, how waveforms affect resolution, and how DRFM electronic attack techniques appear in the RDM.

Quick start

from rad_lab import rdm, Radar, Target, Return, barker_coded_waveform

radar = Radar(
    fcar=10e9,
    tx_power=1e3,
    tx_gain=10 ** (30 / 10),
    rx_gain=10 ** (30 / 10),
    op_temp=290,
    sample_rate=20e6,
    noise_factor=10 ** (8 / 10),
    total_losses=10 ** (8 / 10),
    prf=200e3,
    dwell_time=2e-3,
)

waveform = barker_coded_waveform(10e6, nchips=13)

return_list = [Return(target=Target(range=0.5e3, range_rate=1.0e3, rcs=1))]

rdm.gen(radar, waveform, return_list)
